I bought a controller for my computer so that it could be easier to play Oblivion every thing works except the look analog help btw the analog is not broken

I had exacilly the same problem. Unfortunatly there is no way to fix this. What i did, was i swapped the sticks round on the options. So that the left analog stick is to look around and the right one is to move. But you will have to get used to it.
