Ok, i have a dual card rig. primary card is a 2900XT for my 2407WFP and 2007WFP, secondary card is a X1600 for another 2007wfp. Running Vista. Latest Cat's installed.

Running WMC on the monitors with the 2900XT result in the vid card crashing and WMC acting extremely unstable and unresponsive. Moving it over to X1600 monitor and it works great :\

Any ideas?
