I'm trying to write a MIDlet using J2ME, MIDP 1.0 and CLDC 1.0
The MIDlet must be able to run in the background upon user request, which is done by providing a "Hide" menu item.
Whenever "Hide" is selected the MIDlet does the following:

Display.getDisplay(null);
notifyPaused();

This works well using the J2ME Wireless Toolkit 2.1
But when using a Nokia 3510i, Nokia 6310i (or a Siemens MC 60) there is no effect.

Any help out there?

regards,
