I've checked the connections.
The RTS was connected to the reset pin, but via 10k resistor. Just tried with that jumpered out, but it doesn't seem to be any different.
The USB FTDI module, usually used to communicate/program the Pro Mini, has a DTR connection which is connected to the reset pin. That resets the arduino before download commences and works fine..
There is no DTR available on the BT module, only RTS. CTS on both modules are linked to GND(0V) by the Arduino.

I've tried setting the baud rate to 57600, both in the sketch and BT comms.
I've tried selecting the Arduino BT w/ ATmega328 as the destination board.
That sets the 'Overiding Baud Rate' to 19200.
(Shown in verbose output screen).
It looks as if, launching the IDE interupts the BT comms and when selecting Tools menu.
I guess, unless some code is added to specifically account for this, it's not going to work.
That's beyond me....
Thanks for the suggestion.
Here was the verbose output when Arduino Pro Mini 328 was selected.
