Thanks for all the PRB references in the KB. Even though the behaviour is documented, it is still a bug, IMO, because the behaviour is not even consistent. In my example code, right click on each combo. The first shows the ReadOnly property as .F., the second shows the ReadOnly property to be .T., yet both can be changed.
