Xcode opens to a no editor screen
I'm interested in making desktop widgets. I'm running OS 10.8.4 and downloaded the latest version of xcode 4.6.3. I go to run xcode and I get a blank screen with the message No Editor. The machine locks up and I can only get out of it by doing a force quit. Any help would be appreciated. Thanks.
