At some point in the past month, drag and drop within Dopus has stopped working on my setup ( Windows 11 Home, Microsoft 365, Surface Pro 8, i7, 16GB RAM, 1TB HD). I get a "no-entry" sign when I try to drag a file or folder - any file or folder. This happens as soon as I hold down the left mouse button and try to drag; I don't actually have to drag it past the "border" or "frame" of the file or folder's current folder. It also doesn't matter if I have one pane or dual-panes visible. However, I can select a file or folder from within Dopus and drag it (out of Dopus) to the desktop or an external program - to Outlook, for example, to attach a file to an email - without issue. Nothing has changed with this setup - no new software has been installed. In fact, I deleted my user profile and rebuilt it several days ago thinking there was corruption in my old profile. No change to the behaviour.
I have checked preferences and only see File Displays -> Mouse -> Allow drag and drop onto files and folders as a possible candidate for impacting this behaviour. It is selected. I can't find any other Dopus setting that might impact this and drag and drop works fine outside of Dopus.
I use Teracopy and it works no problem (I can have a dual pane lister open and use either the copy or the move Teracopy commands to copy or move files between folders, no problem. I run Malwarebytes Premium as my secuirty package and use AdGuard. Can't think of any other potential conflicts. Have used Teracopy, Dopus, AdGuard, and Malwarebytes together for at least five years (I added AdGuard around that point, the other three have been used together for at least 10 years) and all four with Windows 11 since October 2021.
My first thought would be an interfering shell extension, as they hook into drag and drop. You could try disabling them all to see if that resolves the issue?
That part is normal. You can't drag a file to where it already is, so the cursor will indicate nothing will happen until the mouse is over a different folder/panel.
Holding Ctrl should let you copy the file and change the cursor, even if it's being copied to the folder it's already in.
Dang. No joy there (although I am enjoying the minimalist context menu!). I disabled what context items I could find in settings for various software applications and uninstalled several apps and then restarted the computer. No luck. Not a wasted exercise though as it forced me to uninstall several programs I haven't used in years and disable context menu entries that I don't use as well.
Hi Leo - sorry, your reply must have posted while I was writing mine to xraale.
I did try holding the CTRL key (and the ALT and SHIFT keys as well) but this makes no difference. I just tried opening two listers and having them side by side: I can't drag and drop between them either BUT I can drag and drop from a lister on one monitor to second lister open on another monitor.
I started answering your question in detail below, but in the course of testing different scenarios noticed that the pop-up hint above the file as I dragged it was cycling between locations on my computer within the destination lister. A dim lightbulb went off and I unplugged my external devices and monitors and opened a dual pane lister. I can drag and drop between panes in the same window without issue, so will try figuring out what attachment is buggering everything up. This looks like faulty hardware. I'm embarrassed not to have thought of this much earlier. Leaving my notes below in case anyone experiences this going forward and lands here after searching for similar behaviours.
It doesn't make any difference what folders are open, what files I am trying to work with, nor if I am dragging from right to left, left to right, top to bottom, or bottom to top pane.
I've just replicated the scenario I was describing above with a single-pane lister running on each of my three monitors. My main monitor (Surface Pro 8 screen) is in the middle and two Samsung monitors are to either side of it. I created a .txt file and am able to freely drag and drop it from any lister to any other open lister. This lister on my monitor was open to a nested folder on a USB-A thumbdrive, the lister on the left monitor to a Temp folder in my OneDrive Documents folder, and the lister on the right to a dual-pane lister with the left pane open to my root Documents folder in my Windows user profile and the right pane open to the Public Documents folder. I can't drag anything to a dual-lister window if I have to drag the file across the "closer" lister pane to get to the second pane.
