Not really new to dual boxing just took a really long break from it, due to work and real life stuff. well anyways finally got back on wow a couple of weeks ago, and for some reason i can not have my 2nd monitor even enabled if i want to be able to actually play wow on one screen.

on the login screen i move the mouse just a tad and the graphics lag for 2 seconds and then go back to normal if i don't touch the mouse (which also skips across the screen).

any suggestions on what i could do to improve this?

thanks in advanced.
