Hi...just a couple of crashes to note... 1. Had a fatal system crash on a macbook using 1440x900 resolution when parallels window was minimized, then jumped into parallels and tried to make it full-screen. This is probably too vague to help with anything. 2. Noticed horrible slowdown when using Parallels at the same time as a Rosetta app called TimeTool which I use to track my billing hours. Parallels was literally choking into a spinning wheel of death every few seconds. 3. About 50% of the time, for no apparent reason, when opening Parallels it claims there's another version of Parallels already running this virtual machine. Checking the activity monitor, it doesn't appear that there is. Still, am very impressed by this product and would probably buy it if the bugs were ironed out. At the moment, I don't feel safe using it beyond testing out websites...
