NSPopUpButton under Leopard?

Hello!

Sorry to bother with such a lame question, but neither google or my own
research came up with any specific answers.

I'm struggling to create an app, that uses NSPopUpButton. Under Tiger, with
old XCode and IB, when I've associated the menu with NSPopUpButton,
I could change selected item manually and user could select new item from
the UI without any problems.

Now, when I've migated my project to XCode 3.0 and new IB, it seems not to
work.
When I'm selecting new item from the UI, still the old item stays selected
(only change selector is called). Also selectItem: and selectItemAtIndex:
does not seem to work.

Have any of you had this kind of the situation before?
What such a lame programmer as I could do wrong in here? :-)

Thank you in advance.
