Good. That means, one of you toolbars, or add-ons are giving you a problem.
In IE, go Tools>Internet Options>Advanced tab, and click on "Reset" button.
Everything should be working fine, now.
If so, you may start re-enabling add-ons/toolbars, BUT only one-by-one, until you find the culprit.
Main suspects - toolbars: Google, Yahoo, etc.
