Thanks for the reply NotAnIllusion,
Ok, so let's put #1 aside.
as for #2:
assuming the simulation is now in the single-player configuration screen, and al there is left to do is click 'go', what is the proper message I should send to start the race?
as for #3:
I need it to stop, and go back to the single-player screen (as described in #2), not to the start screen. as far as I have seen, I can send keystrokes, but no keyboard shortcut for the single-player mode?
Thanks again
