I'll try. The operating system itself seems flawless. Opening VB sometimes will freeze as soon as I attempt to boot the XP guest OS. Sometimes it will freeze after it is completely loaded and anywhere in between. Then sometimes it will cause my whole system i.e. including LM to freeze. Then it will sometimes crash my system giving me a totally blank-black screen and sometimes it will crash LM but the system will recover itself and relog back into the main desktop. This only happens with LM7, not 6. It really is random, but I never get more than 7 minutes into XP guest OS.
