[AccessD] Error: -2147352567 ??

The error description is 'Update or CancelUpdate without AddNew or
Edit.'  

I've checked for this problem and can't find it.  This occurs repeatably
(at least once a day) in the after update event of a several different
comboboxes on a subform (so most of the time it doesn't happen).  The
subform is bound to a table that is on the many side of a one to many
relationship with the table that the main form is bound to.  This is in
an AXP split database, FE and BE are both mdb's.  The comboboxes use
snapshot queries as their row source.

Has anyone seen a negative error number like this?  I couldn't find it
on the MSKB.
