[Sndobj-devel] Odd behaviour?

[Rory W. <ror...@ea...>]

I'm getting some odd behaviour with a simple Sndobj app I'm building 
with wxWidgets. I have the following simple code:

...
SndWave  input("Radiohead.wav", READ);
SndRTIO output(1, SND_OUTPUT);
SndIn signal(&input);
output.SetOutput(1, &signal);

   for(int i=0; i<dur*(DEF_SR/DEF_VECSIZE); i++)
   {
	input.Read();
	signal.DoProcess();
	output.Write();
   }
...

When ran as a command line app it works fine and plays the audio. If I 
insert it to an OnButtonPress() method it causes a crash. I know I 
should be using threads but I'm trying to show some students why threads 
are necessary. Running this code should play some audio even though the 
  application will freeze for 10 seconds. I'm using windows and MinGW. 
Any ideas?

Rory.
