How to re-organize folder tabs in a single Directory Opus 13 lister

I recently purchased a Directory Opus 13 version. I am excited with it.

I have a question on how to re-organize folder tabs in a lister.

I am using a Directory Opus lister with multiple folder tabs (shown at the bottom).
I used to move a folder tab by drag-and-drop it between the existing tabs.

However, this event action (drag-and-drop) ends up with creating a new lister instead, by default in Directory Opus 13.

Which options allow me to change such default behavior to reorganize folder tabs by drag-and-drop?

Thank you.

A good starting point is to check, if you have > Preferences > Opus Start > Explorer Replacement > Open new Tab instead of a new lister checked. That would prevent you from getting multiple listers. From there you will have a multitude of options, like tab groups. Then you could arrange your tabs and right click on the tab's row to save your first tab group. You can also drag around tabs, or give them border colors, link them, etc.

That's coming from the fact you probably have enabled the labels of the tabs to be considered as folders for drag and drop.
You have two options:
First one is to disable that: Settings/Tabs/Options then look at the screenshot below.

The other option (which I prefer) is to move the tabs by selecting their icon instead of their label/name.

Dragging between tabs still works, but you need to drag on to a tab bar, not anywhere else. Dragging a tab out of the tab bar will split it into a new window, unless it's put into another tab bar.

If that is going wrong, let us know your screen resolution(s) and DPI(s), including which screen is the primary monitor (if there's more than one), and the version of Windows, and we can see if we can reproduce the problem.

(Assuming you're on the current version of Opus 13. If you're on an out-of-date version, please try updating first.)

Thank you so much for your help.

Unfortunately, the option for Explorer Replacement turns out to be not related with my issue.
The option for Folder Tabs worked for me, which PassThePeas pointed out.

In brief,

I tried to use "icon" instead of "label/name". However, I was able to make my aimed event by using "label/name" with the option as ON. But, my drag-and-drop action creates a new folder tab instead of moving itself.

In detail, I made a demo below as Leo suggested. This behavior looks like a bug when with multiple monitors. This demo is with my primary monitor of display resolution is 2560 x 1600. I am using Microsoft Windows 10 Version 1903 (OS Build 18362.1256), but I don't think that this Windows 10 is out-of-date because many people are still using it.

In Screenshot 1, I chose the option ON, "Treat the label as folder when dragged or right-clicked" in this demo.

In Screenshot 2, I created 4 folders, shown as 4 different folder tabs.

In Screenshot 3, I am dragging "Folder4" tab between "Folder1" and "Folder2". As you see, "New tab" context message gets shown while I am dragging, but very carefully.

In Screenshot 4, I dropped it between the "Folder1" and Folder2" tab. However, a new folder tab has been created instead of moving the "Folder4" tab itself.

Drag and drop by icon moves the tab.
Drag and drop by tab name/label makes a copy of the tab (if option to treat label as folder is on).
This is very coherent behaviour as if you try and move a folder from within a lister between two tabs, this will create a tab for that folder. So, if you treat tab labels as folder, it behaves in the same way.

With PassThePeas feedback, I made another demo below.

In brief, this demo shows that the folder icon does not behave to move a folder tab. It always creates a new lister instead of moving itself.

In Screenshot 5, I disabled the option "Treat the label as folder when dragged or right-clicked" as PassThePeas suggests.

In Screenshot 6, I click and drag the "Folder4" folder icon (but not the "Folder4" label). As you see, there is no context message "New tab" shown while I am dragging. Though not shown in the screenshot, my mouse cursor is between the "Folder1" and Folder2" tab.

In Screenshot 7, I dropped it. However, a new lister of "Folder4" is up instead of moving itself between the tabs.

In sum, the "drag-and-drop" action event in a Directory Opus lister in my laptop always ends up with a new lister created up, instead of moving a folder tab.

Is there any solution for this issue?

Thank you.

Considering the screenshot #6, it may be something related to DPI.
On this screenshot, the tab you're moving is not in a state where it can land in a new tab bar: you can see that because you have some kind of a shadow window with a small lister.
If you drop in that state, this will create a new lister.
When you're over a tab bar, that shadow lister window disappears, and you only get the tab itself drawn on screen.

Since you're saying your mouse is over the tab bar at that moment, only thing I can think of is something related to DPI : what you see is not what Opus sees.

You could try to move vertically the mouse "on a virtual line crossing the current lister" to try and find a spot where the shadow window disappears and if/when found, drop the window.
This would only confirm but won't be really usable ...

EDIT:
Screenshot when moving the tab over the tab bar (mouse not shown, but is on the icon of "Bibliothèques" while dragging):

Screenshot when moving the tab somewhere else (mouse not shown but is in the top left of the shadow lister appearing over the current lister that tab has been dragged from - in the drawn red rectangle):

EDIT2:
Looking at your screenshot #6 again, what seems strange is that you're saying the mouse is between folder1 and folder2 tabs, and the shadow lister is nowhere near that.
Do you confirm the "shadow lister window" upper left corner is not attached to your mouse pointer and moving with it?

Thank you for your nice feedback, which gives me some idea to try.

As a quick answer,

Do you confirm the "shadow lister window" upper left corner
is not attached to your mouse pointer and moving with it?

No. Though my screen capture did not catch my mouse pointer, my mouse pointer was between Folder1 and Folder2 tab, as similar to Screenshot3. Whatever I click and drag (folder icon or folder label) if with the option OFF (shown in Screenshot 5), it always ends up with like Screenshot 6.

For info,

I am using 3 monitors including my laptop centered between two monitors of display resolution 2560 x 1440. The previous version Directory Opus 11 has been working for moving folder tabs.

I hope this makes sense to you, and I am sorry for my short reply--busy works!

Thank you.

What are the three monitor DPI / scaling amounts set to in Windows?

Thank you for your feedback. Below is the specification of my monitors, including a laptop as the primary one by which I made this demo.

Primary monitor of my laptop

17" WQXGA (2560 x 1600)
2560 x 1600 in use
125% scale

Two secondary monitors

27" Quad HD (QHD, 2560 x 1440)
2560 x 1440 in use as landscape and portrait display orientation
100% scale

I could not find which DPI for each monitor, but you should be able to estimate it from the monitor size and their native display resolution.

For information, I attached a screenshot for the primary monitor setting.

In sum, I have upgraded Opus 13 version from Opus 11. After upgrade, Opus 13 folder tabs won't move in all 3 monitors with the setting of Screenshot 5 (or 5th screenshot). Instead, the drag-and-drop always ends up with creating a new lister shown in Screenshot 6 and Screenshot 7. Although not captured in Screenshot6, my mouse pointer is located between Folder1 and Folder2 tab as like in Screenshot 3 example.

Thank you.

In addition,

I have just noticed that all the listers (that I captured above) has the window label in the top, saying "DPI OVERRIDE ......". I tried to find how to change the label as usual, because it looked strange. However, I couln't find the option. I hope to have it in the next Opus version.

That may be what's causing the problem.

You can fix that by turning off any compatibility settings that are on for dopus.exe and then restarting:

I would like to update you all with good news.

I finally fixed it on my end, and Directory Opus 13 works now for moving folder tabs.

"Windows Compatibility Settings" caused this issue.
I was able to figure it out from Leo's resource at Windows Compatibility Settings / Wrong DPI / Installer misdetects OS

Thank you so much for helping me out in this issue.
