Thanks, but I don't think the 100+ loop is the problem.
Let's see a more extreme example.
I made the left button (Light green) loop all blue dots to play sound every 0.1 second.
(Maybe it's easier to test just on web.)http://dl.dropbox.com/u/31590694/ScirraBugReport/index.html
We can see, the light green button loops sound more than 2000+ times every 0.1 seconds,
obviously insane but it runs ok.
And see the dark green case. It can loop only 30 times per 0.2sec, then crash.
(In dark green case, I remove all blue dots before next running.)
So it seems not the insane sound-play times cause crash.
