John,

The problems result out of a 'fix' I did that prevents windows jumping 
around on screen and being resized and such before the app mainloop starts 
running. It exposed a bug in Control.CreateParams.

Since svn is on the fritz I've attached a patch in the meantime that will 
fix it.

Cheers,
  Peter
