Hi,
I was wondering why my mouse pointer kept changing mode on me. In contact sheet, I always use it in "pointer" mode. However, it keeps winding up in "zoom" mode without me consciously making that change.
Now I realized why this is the case: As you mentioned, the "Z" key in contact sheet does already perform exactly that function - put the mouse pointer in "zoom" mode. So each time I meant to zoom the preview window, but failed because it wasn't selected at the time, I accidently mess up the pointer mode on top. Which I usually don't notice right away either, so it generates another "miss" a few pictures later, when I return to the contact sheet and attempt to use the mouse in what I believed should still be "pointer" mode.
I see why this is hard to improve on the program's side. But still, maybe you could think of a way? Even the possibility to disable the "Z" button in contact sheet completly for those who don't use it (or even don't want to use accidentally) would help.
Regards
