Help! Since upgrading to P7 I am having continuing issues with XP. If I just quit Parallels and suspend XP I sometimes have an issue where my iMac freezes completely and emits a steady slow beeping alarm out of both the external speakers and the internal speaker... So I thought I could outwit it by shutting down XP each time I get out, but then sometimes it goes through an entire check disk when I restart! I like to be able to pop in and out of XP when I want, so this is driving me batty! BTW, running Lion. HELP!
