So, I really want to use my 360 controller for Skyrim on PC. It works great except for one thing: menus. Crafting, alchemy, or even just inventory sorting are very hit and miss with the controller. I'm not really sure what buttons do what, and no matter what I push, I am unable to move the categories left/right, or select items up and down. I was using SkyUI and Catergorized Favorites Menu, and have since disabled them, thinking them to be the culprit. Alas, removing them has not fixed the issue. Any thoughts?

I believe it's the start button in SkyUI but, I'm not positive. It could be LB or RB?
