DriveComboBoxEx descends from DriveComboBox, 
the problem is in 
DriveComboBox, so unfortunately the problem is inherited by DriveComboBoxEx
As the base class does not have sufficient abstraction, it is unfortunately not possible to workaround this limitation from a descendent class 
DriveComboBoxEx
