I don't use IE6 and if there is a repair option in Control Panel, you may consider using that. Open Control Panel and browse to your IE listing and hit delete, a window will open where you are presented 3 choices; choose repair and follow the directions. Good Luck.
What bugs me is when I open IE(I use 5.50)and then hotmail to compose an email, the blank message window will "jump" once and then it stops and I can begin addressing my email. Sometimes I will start to address the email and I have to start over because the window is not fully loaded--apparently!!
Lots of luck with your IE6 problem.
PS Is your IE browser set as your default browser?
WHOOPS, you didn't indicate which IE browser you use BUT the same repair option is available beginning with IE5.50, I think.
