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: Fault Module Timestamp: 00000000 Exception Code: c0000005 Exception Offset: 06816440 OS Version: 6.0.6002. Locale ID: 1033 Additional Information 1: fd00 Additional Information 2: ea6f5fe8924aaa756324d57f87834160 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?
