Hard to explain, but I'll try.
I have documents folder in dock. I right click, through several folder, to a file.
I release and the file comes up.

Now after couple years of doing this new thing happens. Instead of the file coming up, the folder contents of which that file originate from comes up -- defeating purpose of the routine. any ideas appreciated. thanks.

I've had this happen before. I logged out and back in and it was gone. Maybe I turned on some unknown feature by mistake. Anyway, I only had it happen that one time.

For some reason the dock thinks you have the command key held down. Are you using a third party mouse? check the drivers if so. I had erratic button behaviour with the logitech drivers so switched to USB overdrive … end of problem.

Yes, stupid me, I just did a re-boot and problem went away.

But will it come back?

Yes I have logitech, for many years. Just got the newer mx500 two months ago, great mouse.
