I was 100% sure that you were wrong here, so I wrote my own test-app.
But you're right, timer events are delivered even when the Thing! popups
were open.

But if you try to lock the screen in your test-app, e.g. something
like...

while(evnt_mesag(2000,0))
{
  wind_update(BEG_UPDATE);
  printf("evnt_timer returned at %ld\n", Gettime());
  wind_update(END_UPDATE);
}

...you will see that the timer-events are *not* delivered when your
test-app tries to lock the screen while it's already locked.
wind_update() will block until the screen is released by the other
application.

I think this is the real problem with mxPlay.

Mikro should call wind_update() like this instead:

wind_update(BEG_UPDATE|0x100)

This will not block, instead it will return with an error value (0). So
check the return-value of wind_update(BEG_UPDATE|0x100) and just return
if it returns 0. If not, continue as normal. I think this will fix the
problem.
