This sounds very much like the popupmenu CDEF that I'm working on
right now and maybe I'll introduce it because I should be done with
v2.0 today. The main feature is that there is zero flickering if you
use it non-abusively. It conforms almost exacly to the pictures in
IM V and even has code to center itself within the CNTL bounds if you
want.

I found that it wasn't a good idea to have the max set to the number
of items in the menu because then if you changed the menu dynamically
you can't make the selected item greater than the previous number of
items.

If anyone is interested I could explain how I eradicated the flicker.
