I want to customize the menu in an open message. I've made a C3PO and
succeeded to customize the main menu and the context menu's, also the
context menu's in an open message. But the menu there doesn't react. When
I put a breakpoint in CCommandFactory::CustomizeMenu() the program doesn't
arrive there. I'm using GW 6.5 and C++.

What can I do?

Thanks and regards,
