Well, I've found a couple of things. For one, the line:

txt.setAttribute("width",outwidth.value - outy.value);

Should probably be just:

txt.setAttribute("width",outwidth.value);

Otherwise the further down the list you scroll the narrower the edit 
boxes will get.

Also, I see some very odd behavior in my tree (though not in Neil's 
example) -- whenever the textbox is shown, it is in exactly the correct 
place, but the tree columns expand slightly as if to accomodate it, 
resulting in an awful "bounce".  I don't understand why it's doing this, 
since the two elements are part of a stack and shouldn't really affect 
each other.
