Hi,
I believe that my problem is the same as for this patch, except a whole
lot worse. There are times that all my windows freeze with everything
blank when my mouse is near the screen edges. I also have the problem
that EdgeResistance sometimes does not work but switches screens
when the mouse is just getting to the edge, but then not redrawing the
screen for a long wait.
The question I have is, how to you apply this patch? I have a Sun OS
4.1.3 system. I have never delt with patches before.
