Ran Compressor on Guest XP pro sp2 and all seemed fine, was taking a while so left and in that time the Mac went into sleep mode (I left the VM in normal window, not reduced). When i came back a Mac dialog stated that the compression was done but the VM is locked, tried sending Ctrl-Alt-Del nothing. It is sitting with dialog showing 100 percent complete but nothing, no response. I check the OS force quit and it didnt show as not responding. Upon clicking reset go Mac Hour glass and and now a not responding in Force Quite Upon restart of parallels, it gave me the dialogs of it being open and had to tell it to continue. after restart or VM. XP seems fine, with noticed compression
