ComboBox alpha buttons in TC4.x not shown in TC5.x
In TC 4.x the ComboBox has a nice feature where it shows the Alphabet buttons at the top of the list. This helps when selecting from long lists. This is the "A", "B", "C", etc buttons at the top of the ComboBox popup.
In TC 5.x this feature is no longer available on the ComboBox class. Nor do I see a way to enable it in the documention.
Many of my users really like this feature. Can this be enabled again?
