Since the patch yesterday, I cannot scroll through any list in game. Not inventory, powers, game settings---nothing. I cannot play the game I bought. Please fix this soon so the game isn't a $60 paperweight... except without even the functionality of a paperweight, since I bought it through Steam.

I have this exact same problem! I wondered what was going on -- I played till late last night, all worked fine, and this morning now the arrow keys don't work. If I want to scroll through an inventory, I have to use the mouse, and that is very tricky and uncoordinated.
Also, the dialogue on my game has never been properly synchronized. Characters' lips all keep moving after their dialogue is over. They are all, without exception, like this -- about a second behind the audio track.
Can Bethesda give me any advice on these two topics? Thanks.
