Hi. I got a couple accounts I want to multi-box on one computer. However I have two monitors and want each instance of wow on each monitor (i.e. 1 on 1 monitor, 1 on the other.)

When I try and set EITHER instance of wow to monitor 2 i get a interface/framexml/graphics.quality levels lua :300 attempt to compare number with nil error.

I am trying to run one off one graphics card and one off the other. Can this be causing it? Each monitor is hooked up to seperate graphics cards. No SLI or anything though.
