Using Motif L& F, the file types filter drop-down
combobox cannot be navigated via the keyboard unless it
is first navigated via the mouse (then everything
will behave ok until the application is shut down and restarted).

If we do not use a mouse, we can press DOWN-ARROW to open the combobox
drop-down, but when there are multiple entries to scroll through,
subsequent DOWN-ARROW presses do not work. Therefore, you cannot use the
keyboard to select a different file filter entry.

Again, RETURN key will not select the option in filter-combo.
