IE Address Bar Incredibly Slow when lacking http://

[MadGeek451]

Howdy

Was working on a computer the other day, and the address bar of IE appeared not to work if I didn't enter an 'http://' before the address. I'm working on the owner's other computer now, and it now has the same issue. Un/Reisntalling IE has no effect on the issue. I've done the Ad-aware/Spybot S&D thing, even played with HiJackThis some... no effect.

Any ideas?

Thanks
