LOL, Pescado, I had a very strong feeling that this was the issue. Unbelievably, I don't really have any other major problems with Vista (yet), so I'm not sure upgrading to XP is worth the hassle for me. However, I may change my mind so I appreciate the link.

In the meantime, playing in windowed mode seems to have done the trick, so thank you Jade. 

I've got a really irritating problem, and I'm hoping someone much more Awesome than I can help. 

Basically, I've got gaps in some of the Maxis clothing meshes. It seems to have started with Glamour Life meshes, though not all of them. The gaps appear in CAS and in game, and are always located in the chest, back, or stomach area. It's more apparent when the sim is viewed from certain angles or when the sim moves. I have all the EP's and SP's except one of holiday packs, and my game is fully patched.

Things I have tried:
-Updating my video driver.
-Removing all CC, including hacks.
-Removing/regenerating groups.cache
-Removing/regenerating my user file.
-Complete reinstall

My system specs:
-Vista Home Premium (I know, I know, but I don't have the option of switching to XP.)
-AMD Athlon 64 x 2 Dual Core Processor 5600+ ~2.8 GHz
-3gb RAM
-Radeon X1950 Pro 256mb

This is really driving me crazy because I'm unable to use a large portion of the newer Maxis clothing and their recolors (Maxis or custom). Anyone have any ideas?

Thanks.
