Red and blue flashing lights

I just got a new PC, and reinstalled Second Life. I'm running Vista ultimate with dual 8800 ultra cards. Everything looks fine but when I use a scripted object like a slingo machine or even a chair, I see these red and blue cones of light pulsing upwards from the object. The only way I can seem to make them disappear is by hiding particles...but then I can't see particle effects. Any advice.

Thanks,
Cuff

Go into the Advanced menu (Ctrl+Alt+D) and make sure that Show Updates is not checked

Beautiful...thanks
