Hi, See the attached screenshot. Why does the emacs frame screw up now and then? I only see this on Windows XP. When this happens, I have to restart emacs. Firstly I thought it might be some memory problem, but i have not seen this problem in other applications, like firefox, outlook, etc. So really something goes wrong with emacs? Any thoughts?
