Vista MaxMSP close error

    Jul 18 2010 | 8:44 pm
    Using Vista Ultimate, 5.1.4, i7 based machine, with 6GB of RAM.
    Every time I close Max/MSP it simply crashes out rather than closing properly. Nature of the error is:
    Problem signature:
    Problem Event Name: APPCRASH
    Application Name: Max.exe
    Application Version:
    Application Timestamp: 4bd99849
    Fault Module Name: StackHash_fd00
    Fault Module Version:

    Additional Information 3: fd00
    Additional Information 4: ea6f5fe8924aaa756324d57f87834160
    is this a known issue?
    or is it perhaps a housekeeping issue I need to figure out?
