I just installed an update to Skyrim, but now I want to get rid of it because I can no longer attack with my left hand at all. Because of this, I can't hit with bows, magic, or anything left-handed. I can only attack with my right hand and 'strong hit', so it's costing me a lot of stamina. If I try to hit with left hand my character makes a special move (like he attacks with both swords; not the strongest attack) which isn't what I want either.
Are my mouse button inputs messed up somehow? How do I fix this?
If necessary I can upload a video to Youtube, but hopefully this will be enough.
