So, across several characters, ive come to this same problem: With almost every single jump, I will not land, and will continue to 'slide' for a brief moment before touching ground .Even occurs on flat land. Any ideas? It gets really annoying x.x

Edit: This results in my character's animation (3rd person) freezing as they glide, and makes my course unchangable, as if i were still in the air. In addition, it seems to be related to a bug where i constantly get stuck in things (including NPCs) while jumping about.

I wouldn't worry about it too much. I've been playing Morrowind since 2002 and this seems a common issue in all of the many games and different installs with diff OS's. Personally I think it's kind of cool. If you go to first person, it's not as noticeable. You still glide at times but it doesn't seem as often.
