Re: replacing carbon menu with cocoa

Hi,
I loaded from Nib, as you suggest, and something strange happens -
strange, but near what I need-

If I load a Nib, the new main menu overlaps the old one (and two menus 
coexist)... but new Main Menu redraws "apple" menu too, and disappear 
if I reload the Nib. Finally, if I first "clean" carbon menu, and then 
load bundle twice, everything seems to be working. This is the code I 
wrote:

static sqInt initializeCocoaMenu(void) {
   MenuRef cleanMenu;

   //First we clean the carbon menu
   CreateNewMenu(menuId, 0, &cleanMenu);
   SetMenuTitleWithCFString(cleanMenu, CFSTR(""));
   SetRootMenu(cleanMenu);
   //Then we load the bundle
   [ NSBundle loadNibNamed: @"MarsPlugin" owner: [ NSApplication 
sharedApplication ] ];
   //... twice
   [ NSBundle loadNibNamed: @"MarsPlugin" owner: [ NSApplication 
sharedApplication ] ];
   return sqNil;
}

... but this is ok?

Thanks,
Esteban
