Um, nevermind, wrong OS for the fix. Heh heh!
This will be fixed in 10.6. In 10.5 and earlier, that's just too late, sorry!

The first time the button is clicked, there is a removeAllItems and then the items are loaded in (over 100 of them) but the drop-down list that appears is only a single item tall and the scrollbar area is present, but plain gray with no scrollbar. All the items are present --- you can click inside the dropdown and then drag up or down to scroll through the list --- but you wouldn't know this from the single-item-high dropdown and disabled scrollbar. If one of the items is selected, that is the one shown in the single-line-high dropdown area. I can read back numberOfVisibleItems and hasVerticalScroller and they are correct, but what appears does not reflect these values.
