This sounds damn strange, but there's this really annoying white pixel border in itunes mini player. It's about 5 pixels at the bottom and only appears after expose is used and the window that is in front of it is moved after expose stops being used. If I click the application they go away, but then come back again. I think this only started after I installed Tiger. It's a 1.33 Ghz 12" PowerBook. Any thoughts? It sounds small, but gets damn annoying.
