I have the same problem, but only on MacOsX with MetacardCarbonMach-O.

How to trap (or to delete, or disable) the "Quit MyProgram" in the menu 
which is automatically created  when building an application ?
It is possible to handle the "About MyProgram" by creating a dummy 
"About MyProgram" in the "Help menu.
Is there such a thing for "Quit" ?
