DO v13.3.5, Win 10/11, scroll wheel causes folder tree to scroll to bottom or to top and not a page at a time.
I can't reproduce that here.
How many lines is your mouse wheel set to scroll?
Have you edited the tree's spacing / indentation settings at all?
Also, make sure no compatibility settings are turned on for dopus.exe: Windows Compatibility Settings / Wrong DPI / Installer misdetects OS
Thank you for the quick response!
I am using the "scroll one screen at a time" setting (which works with DO12).
I have not changed spacing or indentation as far as I know.
All compatibility options are turned off.
I am using a Logitech M510 mouse with XMouseButtonControlSetup v2.20.5. I have disabled XMouse and the scroll behavior is the same. (I do not use Logitech mouse drivers.)
Set it back to normal temporarily, and set a reasonable number of lines (I think 3 is the default), then set it back to "one screen at a time". That seems to work.
I'll see if we can support the "one screen at a time" mode better. To be honest I had never seen that before.
Turns out we were handling "one screen at a time" mode, except in the folder tree. I've fixed that for the next beta.
Changing to multiple lines then back to scroll page did not work. Thanks for finding the issue and the upcoming fix!
