Hi. It's not a case of closing individual runways. It is, as I say, simply so that, having set up an arrival runway with its STAR (real-world pilots don't usually do this when they hear from ATC on approach, unless ATC instructs a runway change from that in the flight plan: AFAIK it's done at the departure taking weather at the arrival airport - which can sometimes change of course - into account), should ATC give a runway for landing that is not the one already set (which is often the case at larger airports), the pilot does not go ahead and confirm it automatically - 'cos then I have to ask for a runway change immediately after having confirmed the ATC's runway choice. Just cosmetic, but it always sounds a bit 'daft'!
A checkbox, or even a line that one can change manually in the ini file would be great.
