SubForm Record Delete Warning (2-times)

[ApexData]

I have a subForm sitting on my MainForm.
The subForm is a continuous form and Does Not have its RowSource tied
to the main Form.

If the subform is tested in isolation, outside the MainForm and I
highlight a record and press the delete key, I get the normal warning
that I am about to delete 1-Record. When I Press NO there are no
further messages, as expected.

However, when the subform is tested on the mainform, the Warning that
I am about to delete 1-Record repeats itself 2-times, even though I
Pressed No. What gives???

Thanks
Greg
