   I am adding a piece of source code ( less than 200 lines )
   which should show you the problem. When you run it just
   click on the "File" button, and resize the window, click on the
   "File" button again.

   This may have something to do with the way the help button is used
   also.

   BTW when the fix I suggested is not used then the form seems to
   try to get the maximum size it can ( i.e. the screen size ?? ).

   I hope that I have give you enough.

   Should I fill in some info in the bug report ?
