i am working with parallels since version 4 running on macBookPro with XP Virtual machine. i am using spaces and fullscreen mode so i switch very quickly between the 2 OS. at office i am using an external display connection with a VGA cable.so i can see 1 OS on every display. every time i disconnect the VGA display and put the mac to sleep. i realize that the parallels has crashed when turning on the turning mac again from sleep. this is very strange because after disconnecting the VGA cable everything is working just fine, only after sleep. the parallels is gone!. on version 4 it didn't happened . so for me upgrading to version 5 was a big disappointment . please help.
