Also, if you use the stock menu items (or actions, if you're using GtkUIBuilder), they'll magically change from (e.g.) ctrl-F to cmd-F, which is what Mac users expect.

Are you using UTF16 or UTF32? The leading zeroes in the wchars will make g_print and the NSString import routines think that you've submitted a zero-length string, because they expect single-byte characters. You can test it by transcoding the result of gtk_menu_item_get_label in your g_print statement.

Sounds like something is interfering with the window focus signal switching the menus. You might want to set DEBUG = TRUE at the top of ige_mac_menu.c and see if you get the "Menu Switched" message on stderr when you move from window to window.
