Add items directly to the receiver's menu instead.
Yeah, but the OP is right, the Application Menu and Pop-up List Programming Topics for Cocoa says this: > To implement its menu, the button cell contains an NSMenu object, which in > turn contains several NSMenuItem objects, one for each item in the menu. > Avoid invoking methods on the NSMenu object directly, but instead invoke > methods on theNSPopUpButton instance, which may need to do some housekeeping > before invoking the appropriate methods on the menu.
