    ChemOffice.cpp

 Abstract:

    This shim fixes a problem where a dialog box comes up after
    selecting Gaussian Run.  The dialog box warns of a windows
    error that only occurs because we are shim'ing the app with
    EmulateHeap.  We are unable to remove EmulateHeap since this
    causes the app to AV so the only solution at this time is to
    ignore the invalid paramater windows error message that occurs.

  Notes:

    This is a specific shim.
