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

IEBlog Troubleshooting and Internet Explorer’s (No Add-ons) Mode:

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 or Stardock WindowBlinds.

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.

Hope this helps,
Don
