Never had a problem with this if the comboboxes aren't linked to cells.
Can't imagine what would cause your comboboxes to change and fire your
change event macros.

Sorry, I'm unsure what unlinking it from the worksheet cells means. I've
gone into "Format Control" and selected "Don't move or size with cells",
which lowered the number of problems, but I'm still having issues. I am
not
using "Linked Cell".

Unlink the comboboxes from your worksheet cells and handle this with
code
in
the change event.

This is getting aggravating! I have several combobox change event
handlers.
They work fine most of the time. But at shutdown, for some reason
these
event handlers are firing (which is odd, since the app is shutting
down...I
don't care if they've changed at that point). The event handlers run,
but
when they get to the combobox objects, they are "empty" and I get the
424
exception.

Am I supposed to be checking some property that says the app is
shutting
down or something?
