Running 5 WoWs using windows Vista won't work any way since the memory usage double compared to the XP mem usage while running WoW.

Atleast, I installed Vista hoping for a nice fast game play but instead of using 500mb, it started using 1gb, only running WoW ... ><
But lets no talk about vista ... Just mentioned this because the program isn't compatible(maybe) and even if it was, WoW would suck.
