Re: Plea for assistance...

I may be reading things wrong, but according to the MIDP 2.0 specification:
        "The Canvas object defines several methods that are called by the 
implementation. These methods are primarily for the purpose of delivering 
events to the application, and so they are referred to as event delivery 
methods. The set of methods is: showNotify() hideNotify() keyPressed() 
keyRepeated() keyReleased() pointerPressed() pointerDragged() pointerReleased()
paint()
These methods are all called serially. That is, the implementation will never 
call an event delivery method before a prior call to any of the event delivery 
methods has returned."

This is pulled word for word from the Canvas class description under the Event 
Delivery heading.  I would say that this is a bug in the VM.  (Unless I am 
missing something.)

nope

Could you explain a bit what you're trying to do? If you're processing key 
events I'll assume you have a Canvas that wants to do something in response to 
a key press. Just elaborate what it is you're trying to do and we can tell you 
how to do it.
