Have you fixed this problem with .elm.scrollHeight yet?

If not, you say that you have wrapping in the layer so I guess
you may have tables in them. If so you could get the height of
the tables instead.

Something like:

MenuOption.prototype.MenuOptiongetContentHeight=DynLayer.prototype.getConten
tHeight
MenuOption.prototype.getContentHeight=function(){
	if(is.ie)return this.elm.children[0].clientHeight
	else return MenuOptiongetContentHeight()
}

Maybe this would fix your problem, if not DynAPI's.

I found that on IE5/Win, if you reduce the size of the content of a layer,
.elm.scrollHeight doesn't register it. Don't know about other
versions/platforms.

Maybe you could try .elm.offsetHeight - it doesn't work any better than
.elm.scrollHeight on IE5/Win but it works differently on a Mac.
