   8 //              - restruction of Variable declaration
   9 //              - to prevent Warnings under MingGW32

  11 //              - mNoVertScroll TRUE = no / FALSE = Original Code
  12 //                the Original Code Paints a Vertical Scroll in wxPagedWindow
  13 //                which is not needed in this Version. Use TRUE for this.
