Setting the image of an NSPopUpButton in IB?

I checked the archives and didn't see anything. How do I set the image 
to display in a pull-down NSPopUpButton using Interface Builder 3.0? 
No matter what I type in the image field, the field is always cleared 
out, and no image is displayed. I also tried setting the image in the 
first menu item (changing the pull-down back into a pop-up to do so), 
and this time the field didn't get cleared out, but no image was drawn 
in the menu item. I'm going to try this in code next, but shouldn't 
this just work?
