yeah, this is on my desktop PC, i have a cheap dual output card in it, connected to two 17" CRT monitors (i'm hoping they die before too long so i can justify the purchase of two 22" LCDs)
once i enabled that, it worked just fine. i think i had to hit tab and go to video options and enable it...but i could be wrong. i can't go upstairs and test it now because we just put the kids to bed and if i go up there too soon, they will hear me and start crying
