If you interact with the menu bar, drop down menus and popup menus, there a few usability problems.
1) Run HelloMenu
2) Press and hold on Edit (the menu is shown)
3) Move the mouse over Undo
The Undo item is not highlighted. If you release the mouse over Undo, then the item is highlighted but you need to selected again to activate it.
The is a problem because users are used to "swiping" drop down menus on mouse press and releasing over the item that they want to select, all in one gesture. Mac, Windows, GTK, Motif all work this way.
