Here is the issue: I got Macbook AIR and MacOSX 10.7.4 installed. I installed parallels desktop 7 trial and Windows8 on top. Each time MacOS goes to sleep when Win8 is running it freezes for a couple of minutes (just busy mouse pointer and no reacton to pressing any button) Is there any patch to fix this bug? It makes the application completely unusable. Tried VM Fusion. It has it's own disadvantages too, but they're not so significant as making laptop dead for 2 minutes.
