Appearance Edit goes crazy-Help!

Ok, whenever I right click on my avatar and choose to edit my appearance, everything flows normally but then I get these strange, rapidly changing textures all over my avatar. The modifiers dont show what they are suppsed to either. On someone else's computer they normally see a slider and two pictures of two extremes (such as a bald head and a head with a lot of hair or a short nose and a long nose). On my computer, those two extremes are replaced by rapidly changing textures as well. Often, other avatars clothes are doing the same thing. Can anyone help me fix this?

Happens to everybody. That's been happening to me since I first joined SL. >.<

Odd question, is your graphics card on the supported list under SL's requirements? (sorry, don't know the link offhand) Curious to know if maybe that would fix itself given the right card.
