Ok I bought a new computer with Vista and an ATI HD3200 graphics card. Now a few weeks ago when I first installed SL it did the driver out of date error, so I updated. It worked, but for some reason other things freaked out. Got my laptop replaced and took a chance at a fresh SL install with no update and it has worked fine.
The only problem I've just started having the last few days is crashing when I try to teleport. Any one esle had this problem?
