I committed new stuff. Please, try again. I fixed some crashes I found 
in the Win32 version of KMdi when switching the UI modes around. Seems, 
only Toplevel mode still makes trouble.
Though I get a KDevelop crash e.g. when switching from MDI-IDEAl to 
Childframe. See below. Has anybody an idea what could be going on?
CU, F at lk

P.S.:Also KDE-3.0 users have the KDE-3.2cvs dockwidgets and KMdi through 
the compatibility lib in kdevelop/lib/qextmdi.
