I am a big fan of Windows7, i really enjoy it. However recently i have been getting a weird error. When i scroll of my icons (Let's use internet explorer for example) to choose between my several different open pages, alot of the times the window when scrolled over will disapear before i can click on it, so i have to scroll over it several times and click really fast before i actually get the window. I also notice that when this error occurs the page window outline flickers occasionally, as if something were downloading. I have rebooted my computer several times, and it has not resolved the issue. I remember reading about this issue several months ago.
