ARCADE freezes between trials #31
Description
This is a rare but unforgiving problem. Sometimes ARCADE finishes a trial and then stops. No new trial is started. None of the buttons are responsive. The only solution is the run kill_arcade.bat. It makes me nervous because this will certainly happen during a real experiment, some day.
I am pretty certain that this freeze occurs between trials because I get my cleanUp state's onExit function to print "Finished", which is always printed. The cause is somehow a non-deterministic. It's rare and I do not know the exact conditions that lead up to it.
It could be that it is connected to pressing the "Pause/Quite Session" button in the Control Screen. At least, this was the case in the most recent freeze that I saw. Perhaps there are cases where the pause window fails to appear, for some reason.
I guess that the only way forward is to pop some logmessage( ) commands into SGLSessionArc.mRunSession to see how far it gets before the next freeze.
