I have the latest photoshop and latest Mac upgrade....
The last times I have used photoshop I get stuck with a little image on the screen. It is like a mini icon of on one of the files I have worked with, it will be on top of any thing, program or image. I can not move it and I can not get it to go away, it is just stuck there on top/in front of anything open on the computer.
What to do ? Is there a bug in my program or my OS ? It goes away when I restart, but then a new image will do that.
Can you post a screenshot of what your seeing?
