I cannot reproduce this in a test app. The behavior was changed for
10.5 - before that comboBoxWillPopUp was too late to modify anything
impacting the drop down position of the combo box.
What OS are you on?
If you could file a bug with a test app, that would be very helpful.

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.
