When scrolling either vertically or horizontally, a random range of client rows becomes selected for no particular reason. The user then must waste time unselecting.
I noticed that today, theres always a one highlighted, so I cant go to File > Open and choose a file from a different place...it automatically opens the highlighted file.
I'm sorry for the frustration. We'll look into this - I see the issue. Thank you for reporting it.
Not justifying, but calling out - you can click "none" in the toolbar to deselect clients. Hopefully though we'll get this fixed in our update next week.
Also.. I noticed the "reason" (not justifying).. for me it's when the cursor goes outside of the scrollbar as I scroll. If you keep it on the scroll bar the whole time it's ok.
