Error $0E03 means that some RESERVED bits in the wmTaskMask field of the
extended task record you passed to TaskMasterDA were set.  The problem is
that you're taking a pointer to an *event record* (16 bytes) and using it
as a pointer to an extended task record (more than 16 bytes, including the
wmTaskMask field, which you must set).

So:  copy the event record into your own space, set the wmTaskMask field
to something valid, and then call TaskMasterDA with a pointer to your
own record--don't give it the same pointer the Desk Manager gave your DA.

Messages stay in the MessageCenter until somebody deletes them.  I don't
think the system ever deletes message 2, and I hope some of your weirdness
goes away once you start calling TaskMasterDA as outlined above.
