I have a weired problem. My computer use XP and IE6. About three weeks ago, I installed IE7 Beta. A few days ago, a weired thing happened: When I tried to open IE, it just stopped when it was initializing and shortly closed itself. When I tried to open any folder (my computer, my document, control panel), I simply couldn't. the only thing happened after I clicked on "my computer" is that the desktop refreshed itself. What i do is restored to a previous version of windows and delete IE 7 beta. But with the original IE version, the same problem happned again. I am really crazy with this. Please help me! thank you.
