overflow scroll on treemenu sub-menu

hi guys,

i am using the treemenu bolt-on module, and it's working very well for me. however, i am trying to use the overflow="scroll" property so that child menus will have a scrollbar, thus allowing a long list of items in a small vertical space. it seems like it really wants to work as i can get it to scroll sporadically, only if i preview it in my html editor, then flip to a different preview pane, and then flip back to it (although the child menu retains it's previous full height spacing). very odd. in firefox, it appears to accept the menuheight attribute, but no scrollbar. IE appears to accept neither the height or the overflow. i'm hoping someone can take a peek at it for me and see if they can figure out a way to make it work.

thanks, as always, for any help...

treeOffset=0;  // Used to set the offset of sub menus

offcolor = "#00A19C";

I may be wrong on this but I don't think overflow=scroll is supposed
to work with the tree/collapse menu. I think right now the menu
has to do a lot of figuring as to the height of the main menu, then
of the main items, so it can figure out where to position the submenu
that is being clicked, so I would guess it figures out the height of the
submenu also, I'm not sure how trying to make it an overflow=scroll
would interact with that figuring that's in the program now.

Of course, I could be totally wrong on my thinking here. ;)

I believe you are correct, Ruth.
