I have provided a video below showing that with single click mode enabled, folders will automatically expand when you hover over them. In the video I am not clicking any mouse button or hitting any keyboard keys. This behavior occurs regardless of if "expand folders when dragging over them" is disabled or enabled. I can confirm that folder expansion works correctly under the same configuration but with single click mode disabled.
That's by design, we figured if you don't like having to click on items to select them you probably don't like clicking on them to expand them either.
It should only happen if you hover over the expansion button itself.
I agree, I personally prefer to save clicks. The problem is that you can trigger these by accident, particularly in list view. As you can see in the video, you don't so much need to hover over the expansion button, you can really just slide your mouse across a bunch of them and they'll open. So for example when you are in list view I've found mouse movement on the Y axis particularly prove to cause folders to expand, so if I'm moving a column over and up there's a decent change my mouse will pass over one of the expansion buttons and open that folder unintentionally. Does DOPUS use the same value for single click selection speed as it does to expand folders on hover? I have mine set pretty low.
I've also noticed that the current selected folder does not expand on hover, you have to manually click that to get it to expand. This can be quite problematic in single click mode as your selection changes automatically on hover, which means that if you are moving your mouse over to the expand button but aren't fast enough the folder will become selected and you will then have to click the expand button anyways.
Yes it would be the same speed; with the default settings you have to hover quite a while before the folder expands.
I would like to suggest the option for the folder to open on hover over the expansion button separate from single click mode.

Just to confirm that's windows double click speed correct? I was messing around with the setting but it didn't seem to have an effect (tried restarting DOPUS as well).
Double-click speed, correct. It looks like it's set very low in your video, as selection happens almost immediately when the mouse goes over a folder name as well.
Thanks Leo!
For some reason changing my double click speed doesn't seem to be changing the automatic folder expansion time. I can confirm that DOPUS does recognize the change though as the time it takes for a folder to open after I've clicked on it in single click mode (which is also bound to windows double click speed) increases as I reduce double click speed.
This also raises a question, would it be possible to be able to set folder expansion time (or time to open a folder after click in single click mode) separate from double click speed? As it stands right now in single click mode, both folder expansion and time it takes to open a folder after a click is bound to double click speed. This means if you want folders to open quickly after a click, you have to set a fast double click speed. By extension this means you also are going to have folders that expand very quickly and thus run into accidental expansions.
Another reason to separate open on hover over the expansion button from single click mode?

Experiencing the same issue as @evernessince. Regardless of double click speed setting, automatic expansion happens right as the mouse pointer hits the expansion button. Even setting the speed and doing a full DOpus restart has no affect.
Also, it appears "Single click over icon only (normal behavior on labels)" disables automatic expansion. Is this by design?
I can confirm what you observed with "Single click over icon only" does indeed disable automatic expansion. Yeah, tried the same steps as you trying to get the folder expansion bit to pick up the new double click speed unfortunately to no avail.
@jinsight That's a good point. I can see it being a useful feature for people not in double click mode as well. Maybe it should be an option under File Displays > Folder Expansion with a configurable delay. Wondering if it would also be possible to implement an option to expand folders when the mouse passes over the folder name / icon only when a configured key / mouse button is being held down.
Just bumping this thread for an official response.
There are hundreds of posts to deal with at the moment, please be patient.
The timing should be the same as hovering on an item to select it (it uses the same timer).
To clarify though, it's not the double-click time that's used, it's the system hover time.
This can be set in the registry (I think the old Mouse control panel used to set it, not sure if the modern one does) with the HKEY_CURRENT_USER\Control Panel\Mouse\MouseHoverTime value.
If that's not set, or is set to 0, the default is 4/5 of the double-click time.
Watching your video again, it seems like your hover time is extremely short - towards the end the mouse moves over one of the filenames and it's almost instantly selected.
I think it might make sense for us to change it to use the double-click timer for folder expansion rather than hover time, since it seems like setting a very short hover time isn't that uncommon. We'll do that in the next beta and you can try it out and see what you think.

I think setting it to work off double click speed is a good solution. The fastest you can set double click speed to in windows without manual tweaking is 200, which should eliminate nearly all accidental expansions.
Revisiting this, count me as one of those who would find the expand functionality far more useful if it were separated from the single click functionality or, at the very least, still allowed even when "Single click over icon only" were enabled.
The thing I like about Directory Opus is the ability to customize and tweak to your liking. I do not understand the single click auto expand in one option. I do find double clicking to be a bit too redundant, however, I find the auto expand absolutely infuriating, to the point that I have actually disabled single click and gone back to double and the last time I used double click was Windows 3.1. Auto expand should be separate anyway as it could have its own option tab for those who like it to be able to set what works best for them.
Support RavenDarhk suggestion that auto expand should be a separate option
We've added an option for this in 13.6.6.
