Hi,
The code works fine on the WTK Emulator, but I just can't figure out why it wont work on the N95/Symbian Emulator or phone..
Can anyone please tell me what is wrong?

Thx in advance!

display = Display.getDisplay(this);
display.setCurrent(mCanvas);


}

System.out.println("pauseApp called...");
}

protected void destroyApp(boolean unconditional) {
mCanvas.stop();
System.out.println("destroyApp called...");

How does it not work? Do you get an exception or what?

No exception,

The program starts, and then does nothing..
nothing at all.. no matter what button I push (#, *, 1 or 2)
It should start recording when I push #, yet, it does nothing..

Hello GamezMaster,

.. If Canvas is in the full screen mode and it has no CommandListener, the MIDlet triggers low-level key events from the softkeys and is thus in full control of them. ..

How about implementing a CommandListener with the Canvas object just to see if that makes any difference?
