I use the Exchange Manager APIs to create an OBEX object and beam it via IrDA to the Empeg, and I think when I do a send, this popup is generated then. It's not something that I can turn on or off, because it's built into the API. I could write my own IrDA code that accesses the hardware directly and bypass the Exchange Manager APIs, but it would be a PITA.

Edit: I see what you mean now, turn on Beam Receive before sending, then turn it off after.. I will look into this. (good idea!)
