Object Reference Not Set to an Instance of an Object
I found this problem...I had some VBA code running on the
BeforeSelectionDelete event that was deleting the object. Disabling that
code so that VBA doesn't try to delete the object at the same time VB.Net is
trying to delete it fixed it.
Thanks,
Chuck
