Foc's Drop-down Lists & <alt+curdn>, Expanded drop-down list does not roll up after selection Options

[asavage]

In the OS/2 version (tested in v3.71), the FOC has two drop-down list boxes:

Open file name
List files of type

When using the mouse, choosing the Open file drop-down list's control arrow expands the list, and selecting an item from the list rolls up the list.

However, when using the key shortcut <Alt+CurDn> to open the drop-down list, then <CurDn> and <Enter> to select an item, the expanded list is not rolled up, and it obscures the items in the underlying window.
