When I play morroblivion in Oblivion it is great,but if I just play the original morrowind my mouse does not move my character properly in interiors.
It works fine outdoors though.
I use mwse and the morrowind fps optomizer and have messed with my mouse setting in winXP but it still don`t work.
I use a USB mouse and a USB keyboard.
Any suggestion.?

Ironman, I have no idea! What
Ironman, I have no idea! What the heck? That's a really weird issue.
