1. sometimes windows won't open like they should... like with tabs on IE7, you open a new tab but it won't load the page, won't do nothing, it just opens up a completely blank page (no bar at the bottom or info or anything) i'll take a screen shot next time to show you what i mean) when that happens, you also can't right click anything (menu won't come up) can't restart your computer through the task bar (task bar will be completely blank) you have to crtl alt and del and it takes you to a menu (doesn't just bring up task manager) and you have ot restart from that screen to get rid of it.
new, easier fix... just restart explorer.exe.
