I'm running Win XP SP 2 on 2Ghz MacBook running Build 3170 So far i've only had a few minor problems, mostly found simple workarounds. But I've been having trouble with mouse synchronization. It works fine in windowed and coherence modes, but when i start up a program with its own custom mouse (eg. a game or something) the mouse stops working properly. The regular mouse shows up as well as the custom pointer but they dont move together. THe way i does move varies depending on the program. I can install parallel tools without mouse syncron and it all works fine, but i have to use the release key combination and cant use coherence. Is this a known bug? is there anyway around it? has anyone else come across it?
