Error: "Object or class does not suport set of events" in ..

In Access 2000, whenever any of the controls
on any of the forms in my database tries to
launch VBA (in the form, of, say, an "event
procedures" attached to a triggered event
handler of a control), I get the following
error:

"Object or class does not handle the set of
events"

In which, however, the the error's message
box doesn't contain a "Debug" button so that
I might be able to track down the location
of the problem.

Does anyone have any idea as to the cause(es)
of and possible fixes to this error?

Thanks,
Russell

It turns out the problem in my original
posting seems to have been due to a
faulty install since, after having
found an Office 2000 CD and subsequently
performed a re-install and repair of the
instsallation, the problem in question no
longer manifests itself
