Have been trying to move my sister’s computer to a wireless network. In the process noticed that she was running IE 5, so thinking that making the move to a wireless set up would be easier with IE 7 I installed it. After that was installed, an error notice appeared stating that IE 7 was incompatible with MSN toolbar (she was using MSN dial-up) and asked if I wanted to look for an update. I clicked yes and the system froze up. After reboot, IE 7 will lock up any time I try to do anything in Internet Settings and will not go to any web page. Firefox works just fine on that machine with the wireless connection so I know that the problem is with IE 7 itself. I've tried to reinstall IE 7 thinking something was corrupted but no luck. I have also uninstalled MSN toolbar. At this point I'm out of ideas any input would be appreciated.
