Hello joemiller,

Please note that the NQ does not rollover to the 12-17 expiry month until September 7th.

When I test this on my end, I get a different pop up message first (see screenshot). I select Yes and then I get the pop up message you refer. When I click OK in this pop up message, the drawing object is still there, but no alert.
