I'm having a tough time explaining this but here it goes:

I have solidworks up and running. Sometimes I will do an operation and then I get an alert window (not visible) in the upper right side of my screen. I can't do anything with it, can't read it, can't move it.

I have my main solidworks screen on my right screen and the other stuff on my left screen. Its almost like this pop-up window is trying to go to a window on a third monitor on the right screen (which is not there).

Any ideas?
