Bob.
What are you trying to accomplish that the native buttons do not do for you?
The popUp command, to me, is simply a tool to invoke a display of resident
menuItems that do not necessarily have to live at the button location itself,
and that button not even needing to be visible.
Are you adding a lot of additional gadgetry?
