This is a new one, I ready a weapon or fists and it immediately goes into block mode and sticks there as if I'm holding down the left ALT key. Not in the keyboard, checked the ALT key with other programs and it works perfectly. Deleted oblivion.ini so it would rebuild from oblivion_default.ini, same problem. Deleted all save games, disabled all mods and tried running plain oblivion with nothing else, same symptom. In the starting cell ready fists and the fists immediately go to blocking.
