Hi,
You may have an incompatible browser add-on.
See: http://www.enhanceie.com/ie/troubleshoot.asp
for troubleshooting information.

The troublesome program may not show up as an add-on. Disable other
security, privacy, ad-blocking, appearance tweaking programs to see if one
of them is causing the
problem. Any program that interacts with Internet Explorer could be causing
this. The connection with IE may not be obvious, such as Google Desktop.

A firewall will probably not be causing this problem, but be sure to turn on
the Windows Firewall from Control Panel> Windows Firewall before disabling a
third-party firewall or security suite during testing.

Does this happen if you startup in Safe Mode?

(Shortened) http://snipr.com/1nwvi If not, a startup program (possibly an
unnecessary program) is causing the problem. Go to Start> Run> (type in)
msconfig> Startup tab to see what's listed.

Or this may be a malware problem- adware, spyware, hijacker, trojan, etc.
