TAB is supposed to bring up radial menu. Your controls must be messed up somehow... I forget what it's called, but there's a keybind somewhere for the 'tab command' key...
Oh, i changed that awhile ago after they first introduced the thing, i dont like it that much, and it annoyed me when switching build modes, my pinkie rests on the tab key anywho, so i just set change mode there.
ill reset to default.
Another thing, and this makes me wonder if its not my save but my install, the UI for screenshots(with GUI) has no UI >.>
Edit x2
I dunno what i just did, but i got it working, changed a crap load of settings and it works >>.>
