When I try to scroll the process list with a mouse wheel,
the scroll stops / sticks / freezes at the end of a single wheel move.
Look at the screenshot:
- a hint on yellow background pops up under cursor (cursor is not visible on screenshot, but it's there)
- procexp looses scroll focus
- scroll can not continue
I work this around by shifting a mouse and starting scrolling again, but …
nowadays with these notorious Windows Applications which have human-hostile command lines of insane length …
I hit this bug almost continuously.
Could you, please, fix mouse scroll freezes?
Checked with the latest at the moment of writing Process Explorer version 17.02
System: Windows 11 Pro x64
