Hi Duncan,

Try this:
In your nib, instantiate an NSMenu and delete the two default
NSMenuItems in it, such that your NSMenu is empty.
From your app controller class (or whatever), have an outlet to the
NSMenu as well as the NSPopUpButton that will contain the NSMenu.
Connect the outlets.

Then, do this in your app controller class (or whatever):
NSMenuItem *menuItem = [[[NSMenuItem alloc] initWithTitle:@"Foo"
action:@selector(fooBar:) keyEquivalent:@""] autorelease];
[theMenu addItem:menuItem];
[thePopUp setMenu:theMenu];

I think that should do the trick.

Cheers, Joannou.
