photoshop bug. can't move layer.

psd 21.2.4

Trying to move a layer using the move tool.

I click on the layer, as soon as I move, it switches to a different layer, and moves that.

I've been using psd for a while, so this isn't a beginner's mistake.

Another problem just occurred.  I just went back to the file.  Suddenly, for no reason, it filled my

entire screen.  I had to quit out.  That could be some gadget I haven't used & am ignorant of how

to get it back to normal, but am in a crunch, and don't have time to hunt around.

What is most annoying is how slick and commercial this application has become.

I m constantly assaulted by advertising schlock, when I only want to work in the program.

I never wanted to upgrade to this garbage.  I was forced because the old psd couldn't work

under the new mac upgrade.  Lesson learned.  never upgrade anything if you are comfortable

with your present workflowl.
