I installed IE 7 Beta a while back and really liked it save a few sites that wouldnt' work. I had ditched IE6 a while back in favor of Mozilla, which I use almost exclusively until recently. The problem is, to get into our Pix firewall I have to use IE, but IE7 didn't work. I figured I'd just uninstall IE 7 to get back to IE 6 and everything would work just fine.
Now when I open up IE 6 and type in a URL and hit enter, it tries to open the link in Mozilla. I figured maybe I could uninstall Mozilla and it would work since maybe it was just a default browser issue. After that, I would just get an application not found error message. I have went in and asked IE to make sure it is default browser and set IE as the default browser in Program Access and Defaults.
