Fold out menu to use with frames

Hi,

I'm looking for a menu that folds out to the right and that can be used with
a frame without problems. It needs to be used in a page, that consists of
two vertical frames, with the menu of course in the left frame. Most menu's
won't open outside of a frame, however I found that Bratta's Coolmenu does.
It is a neat script, but not without problems: when you open an external
link in the main frame, the foldout menus's disappears and won't show up
anymore. The same problems arrises when I try to open pages that are made
with Dreamweaver.
So, if anyone can advise of a menu that has no problems with frames, it will
be very welcome.
