I have a problem lately. Sometimes (often) when I minimize windows and/or switch back and forth between them, I'll get a big black square in the middle of my primary screen that won't go away even with an F5 refresh. There are no dialogue boxes indicated and the only way to get it to go away is to end the dwn (desktop windows manager) process. I have to do that twice and then the black box goes away. Problem is, that so does my WindowBlinds skin. I'm currently using Aero Brushed Metal. Haven't tried it with any other skins yet.
What to do?
(I accidentally posted this in the deskscapes forum as it was the only one that had a thread dealing with dwm). Sorry.
