That inversion effect is pretty distracting, indeed.

Fine.  Keith, can you test it?  Just turn off/on the tool bar once with
a normal and a maximized frame.

Eventually it would be to nice to have adding/removing the tool bar obey
‘frame-inhibit-implied-resize’ (it currently works OK for the maximized
frame so the fix shouldn't be too hard).

Thanks, martin
