I have tried a little test:
Which gives in the logs:
So the code is reaching the Log("After sleep") line as I hoped.
BUT with the sub return type set as ResumableSub, the app does not close (which it should when returning True in Application_Error).
Is there any way that the Application_Error sub can work correctly as a Resumable Sub?
