It is possible to ignore penDownEvents by checking for them in your app's
event loop and then not passing them on to SysHandleEvent. But this is
something you would rarely do. It sounds like you may not be correctly
understanding how a Palm app works. The Palm OS is event driven. You write
code to respond to events sent to you by the OS. If the user taps on a
button, various events get generated (including the penDownEvent) and your
code should respond to it by doing something or you should pass it on to the
OS to deal with it in the normal manner (for example, highlighting the
button when it is tapped).
You say "when I press the button during the execution of Myfunction()..."
What are you trying to accomplish in Myfunction() that requires you to
disable pen taps while it is executing? If you really need to do something
in-between pen taps, the normal way to do that is to call your code from
within the event loop. Look at the source code for one of the Palm games
(e.g., HardBall or Reptoids) to see how that is handled.
