Comment 24 for bug 800778

I cannot give exact steps but it happens frequently enough to be able to generate additional reports. Let me know what you need.
I am also quite confident that it is something with the mouse / pointing device. It is HW independent, occurs with two different mouses and once it even happened while I was working with the touch-pad (no mouse attached).
I tend to say that only moving the cursor is enough, no need for clicking, I am not 100% sure.

P.S. It crashed twice while I was writing this.
