Virtual PC freezes machine when exiting - Mac Applications & Software

I recently added another 512MB of memory to my 450 DP Powermac to see if Virtual PC 5 would run faster. This brings my total to 1024MB. When I run VPC with Win 2000 Pro, all seems well until I exit VPC. I can save the state of the PC just fine, but when I quit VPC my whole machine lockups up and I have to reboot. This was running fine before adding the memory. I have even left VPC running for about a day after saving and stopping the virtual machine. Everything was fine until I then quit VPC. ...

    Default Virtual PC freezes machine when exiting

    I recently added another 512MB of memory to my 450 DP Powermac to see if
    Virtual PC 5 would run faster. This brings my total to 1024MB.

    When I run VPC with Win 2000 Pro, all seems well until I exit VPC. I can
    save the state of the PC just fine, but when I quit VPC my whole machine
    lockups up and I have to reboot. This was running fine before adding the
    memory. I have even left VPC running for about a day after saving and
    stopping the virtual machine. Everything was fine until I then quit VPC.
    Bam!

    In all other respects my Mac is running fine with the additional memory. I
    even used TechTool Pro to do some memory diagnostics and they all check out
    fine.

    This is with Mac OS X 10.2.6.

    Any thoughts as to the problem?

    Try removing the new memory. If the problem doesn't go away, then the
    problem is likely unrelated to the new memory and you have some other
    issue. Also try removing the OLD memory. If the problem goes away with
    just the new memory in, then the problem is likely that the two sets of
    memory modules aren't "quite" compatible with each other. When
    installing memory modules, you are usually best off getting the same
    model of module from the same manufacturer. From what I understand, VPC
    ties into the hardware more deeply than most OS X software does, and may
    be more sensitive to slight hardware incompatibilities that otherwise
    you'd be unaware of.

    This is known issue that exists in even 6.1. However I found that in
    6.1 (I can't remember if the option exixts in 5) if you shut down
    windows by closing the window the Mac way and then choosing "Shut down
    Windows" in the dialog box then it doesn't crash.

    I seemed to have solved my problem. I decided to create a new PC and use
    the same disk image for it. This seems to have fixed the problem. Perhaps
    there is some information about physical memory that is saved with the PC's
    state that was causing the problem.
