Bad behaving software PIXEDIT

Hello Be warned... I ran "pixedit", then it wanted me to pick a windows to edit the pixel. No matter what I clicked, it did not accept that... Okay, that is understandable. But then I wanted to stop pixedit.. No way! There just was not means to "get out of" it.. I could not switch to another screen, terminal, nothing. The only solution that I found was to go to my SuSE router box, log in there, SSH from there back to my workstation, and kill that process.. ...stupid software... J. Tamminen
