It still does that.

Never heard of that.  However, our frame management code is rather
different from Emacs's.  Maybe somebody found a way to avoid that (or
maybe XEmacs users don't use those window managers).

Yeah, we've never fixed that.  Of course the developer can position
the popup by hand, but that sucks, too.  But for something the size of
a toolip (typically with relatively small font size, too) and no frame
decorations, it doesn't bug me anywhere as much, YMMV.

If you've got transparency working, maybe that would be worth trying
(transparent background, alpha=.5 foreground?)  Modern browsers also
often fadeout the popup gradually (I think that's an admission that
the design -- using a popup -- is fundamentally broken, but again YMMV).
