The Motif Look and Feel menu behavior has a bug. When and a menu is selected either by clicking on the menu bar or by clicking and dragging, the menu is dismissed when the user clicks on a sub/hierarchical menu item. The behavior that is exhibited by CDE is to display a sticky sub menu, thereby allowing the user to navigate hierarchical menus. The other expected behavior is that if the user holds the mouse down as he/she drags over a sub menu, that menu will appear but will not be sticky unless the user releases the mouse over a sub/hierarchical menu item. The actual behavior that the user is experiencing is that the entire menu disappears.
