[ka-Map-users] Detaching divs from viewport?

I finally have a chance to work with the latest ka-map cvs version, and am
enjoying the new functionality. I am running into an issue with the divs
however, specifically the keymap and tool layers. I am wanting to run the
application windowed (that is to say, not full screen), and it is not
readily apparent how to detach the aforementioned divs from the viewport
(the main map window). Basically, I would like to retain the layout of the
'old' kamap, without having to resort to tables.

Thanks in advance,

At least for my uses, this would be limited to working off the same server,
so no proxy would be necessary.  Addition of a proxy could just be a pretty
generic php proxy that could be included as well for those who need to
access external "services".
