I just installed the trial, but my VM will not stay on in the background. If I leave it running for a period of time, it shutsdown/suspends automatically, and I lose any background downloads I have running in the VM. My Mac is set not to go to sleep. I can't find a similar setting for Parallels. If the VM can't stay on, it's pretty much a deal breaker for me. Is there some setting somewhere that I'm missing?
