  8. Description:
  9. ¯¯¯¯¯¯¯¯¯¯¯¯
  10. This Windowchecker uses a Routine very similiar to the
  11. standard one of PowerWindows. It also replaces the Look
  12. of the Iconify-Gadget. You will get a little nice Smiley!
  13. It looks a little bit strange on Lowres-Screens, but hey,
  14. this is only an Example!!
