Changed debug to Level 4.... ATC gave me Rwy 01L at VTBS. I asked for 01R a few seconds after the ATC instructions ended - Ctrl+Shift+Z. No response (and no confirming little 'beep' to say 'message received by PF3). On the other hand, as I said before, (although I forgot to do it on this flight), the exact same key combination always seems to work OK if you request a change of departure
runway.. only approaching the arrival airport is there no response.
I also don't know why, on being cleared for final, ATC asked me to 'contact Unicom on 0.0' - when, as far as I can see, Bangkok has a full set of COM frequencies, including Tower and Ground. (I tuned to ground manually with no problem, to announce clear of runway after landing).

That's a separate issue of course, but if you can see what happened, from the log... which is too big to upload here (187MBs before compression!). This is a download link:
