Hmm. As far as I can see, LM_SETPROPERTIES is only called in ApplyChanges,
and this is now only called after Loading, on initializing the window and on
property change.
So, yes, you can recreate the Handle. But make sure, you only do it, when
properties has really changed. Otherwise InitializeWnd will loop.
