Im currently run dual monitors on a geforce FX 5200 ulta. I curtrently am using Nvidia's newest driver. When I go to install themes they install fine, but the far right corner always shoots to the other monitor. Any buttons there work, but the rest of the stuff shows up on the right corner of the left monitor. If anyone can help I'd greatly appreciate it.

there are probably 30 threads on this issue already. you will find the problems with dual-head displays and their fixes there.
