Hi Tom and other Mac OS X gurus,
If you add a MainMenu component to your form, then add a File menu item to it, then to this File menu item, add an OnClick event with a simple ShowMessage, that event is never fired. This works as expected under Win32 of Lazarus, but I could not test it on other OSes.

Sub-menu item events do respond to OnClick events, so behave as expected.

Added to bug tracker under bug no. 0011043.

Dominique.
