hi, ive been multiboxing in WoW for a week now and have enjoyed the quick leveling with the new refer-a-friend promo. im only running 2 accounts. today i decided i was sick of alt-tabbing and went out and bought a little 15" LCD (my main display is 24" ws) anyways my problem is that my second WoW wont go up to the second monitor without being in windowed mode, and when im in windowed mode i go from 100 down to 10 fps, which is unacceptable. somewhere i read to get UltraMon, which i did, and it does works with other applications, but not with WoW. ive scanned through numerous posts here and havent found the exact fix im looking for, so any info would be very useful. ill list my specs below if that matters...

Vista Ultimate 32 bit
Intel Core2Duo 6600 2.4ghz
3007 mb ram (really 4 gig)
NVIDIA GeForce 8600 GT

any advice on this would be greatly appreciated, thank you!
