Auto-width correction in popup-menus?

[Shannon V Spires <svspire@somnet.sandia.gov>]

Has anybody written code to automatically correct the width
of a popup-menu item depending on the width of its current
default item? It's annoying that the menu automatically
width-corrects itself when it's pulled down, but it snaps
back to its original width when released, even if the new
default item is too long to fit.
