I just updated to IE 10 and now it won't work. It opens but there's no URL in the address bar, and nothing on the screen, it just starts with a blank page. If I enter a url and then hit enter nothing happens. It doesn't even try to load the page, it's like I didn't even hit enter. So it's basically stuck on a blank page. Also when I click the gear icon in the upper right everything is grayed out except the File & Safety options. I need it to test sites I'm designing so this is somewhat of an issue. Any idea what is causing this? I'm using W7 x64, and the 64-bit version of IE 10. This also happens with the 32 bit copy of IE 10 as well...
