i've been running Windows XP under Parallels 3120 on my MBP (C2D) without any problem whatsoever, ever since it came out. It's so stable that i start to trust it and install it on my MP. The MP has been running the older stabled version of Parallels (1870 or something like that). ...and i got a problem. Coherence doesn't work. there's no way to enable it, either via Parallels Tools or Parallels preferences. now i'm not sure if it's because Parallels coherence hasn't supported MP yet, or because it's still unstable with multiple monitor systems.. but it just didnt work at all. is anyones else having the same problem?
