Hello, I have a Powerbook G4 1.2 GHZ and 512 MB RAM. I was running VPC 6 with win98. After being idle for more than 30 minutes the program would be frozen, everything else would work, excel on mac, word, anything, no problem, just the VPC frozen solid, I have to force app shutdown. I thought maybe win98 prob. Upgraded to VPC 6.1.1 and installed another PC with Win XP. Runs much slower and problem persists. Last night i was working with Win xp, went to sleep and in the morning, FROZEN. Updated WIN XP with all the critical upgrades, and I'm stumped... Thanks for the help..
