A web page with Fireworks 8 Javascript (not CSS) pop-up menus imported into
Dreamweaver 8 works fine on its own. However, if I include the page in a
frameset, the menus appear to work OK (e.g. everything pops up and down when
expected, all the rollover transitions appear flawless, and the pop-ups are
well clear of the frame boundary), but when a popped up menu item is selected,
nothing happens - the top-level menu items are the only ones which still
navigate to their links.

I normally avoid using framesets, but the frameset in this instance has a
useful applications function and I would be loth to remove it
