menu item is enabled, but still grayed out

Question

I have a menu with several items created in interface builder. It looks fine there and \'enabled\' is checked.
But when I run application, all menu items are grayed out.

Answer 1

In case somebody might google this out and benefit, 'Action' method was declared without :(id)sender parameter:

-(IBAction) quit;

Strangely, setAction method in NSMenuItem ate it and didn't complain. Oh well.
