I purchased Parallels Desktop 6 about 5 months ago and it was working fine under Leopard. Now I upgraded to Lion and I'm having a lot of problems while trying to run a VM in full screen mode: the Parallels window "floats" between spaces and I'm unable click on it in order to use the VM. Then I visited the Parallels website and found out there's a version 7 which supposedly works fine under Lion. But wait a minute. I have to pay 50 bucks again? While a VMWARE user only has to pay 30? Of course I would pay the 30 bucks, but not 50, because it's not fair. So if Parallels 6 cannot run properly under Lion I will stop using it and switch to another virtualization app with better support and/or upgrade policies.
