When www.nbc.com iis entered in the address bar, www.m.nbc.com opens. First I thought this was caused by a corrupted shortcut in my favorites, so I deleted it. Then I deleted all cookies, my browser history, and all temporary internet files and rebooted. The problem still exists, even when I try to go to nbc.com using a link on another web site. This is the only url that gives me this problem. I am using ie7 on a Vista 64-bit OS. Help!
