The properties box (database/document/field/etc) has a problem with all the list selection fields. When you click on the list, the list becomes a seperate floating field and the properties box goes to the background. The list still works correctly but you don't have the scroll bar.
This is a Notes problem not Corssover, we can get it to occur with XP. With XP the list is sepearte but (somewhere else on the screen) but it shares focus with the properties box.
