System Error 1400

[kelly]

I get a System Error 1400 and the message says "Invalid
Window Handle" when browsing the net. I have cable
access through comcast. Any ideas or fixes?

This error isn't coming from IE itself - it's coming from an IE add-in
program or toolbar. Try disabling any 3rd party toolbars you have and
running a spy-ware detection program.
