Hi,
Chances are that another program (probably malware) is causing this problem.
If running XP SP2, go to IE> Tools> Manage add-ons. Try disabling
non-microsoft add-ons. If not using SP2, try BHO Demon from

Then you should download, update and run Ad-aware, Spybot and (if running
WinXP) MS Anti-Spyware (Beta.)

Or...
A legitimate program running in the background may be causing this. Disable
(for diagnostic purposes) programs such as pop-up blockers, security,
toolbars and other add-ons for IE, anti-virus, etc. Take a look at any
program that might be interfering with IE. You may have to reinstall, or not
reinstall, a program.
Hope this helps,
