Has anyone found a fix for this yet? The lack of up/down movement in 1.3. I want to use SkyUI but need 1.3 of Skyrim which won't let me look up or down. Is there a fix?

What lack of movement is this? Have you made sure to use default inis/control mappings, and that the gamepad option is not ticked?

as long as you disable the broken ini "fix" that people found for the 1.1 issue, 1.3 mouse movement works fine.

Really? Can you link me to this fix please or tell me what it is?

In earlier versions of the game Y axis movement was a problem so people modified their ini files. Since that was fixed in later patches these ini file modifications aren't needed, and in fact cause problems rather than solve them.

Delete your ini files and reverify steam cache before launching the game so that they are rebuilt as defaults (backup just in case).

Thanks, worked great.
