Tested the -425 version (as downloaded, so Dirk's build).

1) Functional: somehow I expected the selected choice for the previously 
used connection type to be saved on exit and restored at a new start. 
Without looking at any code change (yet), I assume that this is known. 
As most users will use the same way of connecting all the time ... this 
would be a useful enhancement.

2) Something that is not new (so not related to this specific set of 
changes), is that during a transfer, the Quit button does not quit, but 
only moves away from the download screen. For my OSTC3, there is a 
relatively simple workaround: just disable bluetooth on the mobile 
device, and quit the download on the OSTC3. It would, however, be much 
nicer when the quit, actually quits the transfer, and (for an OSTC3) 
sends the needed <end of communication> to get the DC back in 
non-download mode, before is taking forever to timeout.

Despite my 2 remarks ... a very nice and useful change.
