This sounds like the dzen and xmobar aren't lowering themselves when
they restart. I thought that was default in xmobar, but you can
explicitly add `lowerOnStart=True' to xmobarrc to tell it to do so.

With dzen2 IIRC it uses -e 'onstart=lower' to do the same thing. Note
that this disables all the other dzen event handlers so they have to be
re-added. Only applies if you use things like mouse-over to open the
slave window, but most xmonad users don't use such things. There's a
full list on:
