You are right Dirk, RInside overrides what is specified because the function myAskYesNo doesn't actually ask, so this explains why there is to termination prompt under Windows. This does not change what happens under Linux because this function is assigned to a Windows-specific callback. Under Linux the confirmation message appears.
The current status is that the example seems to work using R-devel, but not using R-4.2.2.
