Do you use PG_TimerObject for your timing? As far as I could see from
the code, it bypasses the event queue in favor of a direct callback, so
I am a bit surprised that it doesn't work.

Second surprise on a short glance is that uncommenting the code part
helps. Does the timer function send user events? Because all other
events are sent to the capture object only in
PG_MessageObject::PumpIntoEventQueue().

If the timer function does send user messages, then uncommenting this
will indeed help. Since this if-clause is redundant and blocks
processing, it should even be deleted.
