// Fix Netscape 4.x bug where the clowns forgot to update half the stuff 
// when the page is resized.
//
// Also aware of the Netscape 4.08 bug where the clowns send off too 
// many resizes.
//
//
// To use, do a:
//     <script language=JavaScript type="text/javascript">
//       till_reloadPage(true);
//     </script>
//
// For regular pages, do this in the head of the page.
// For frames, do this in the head of the page with the framesets.
// Or you can just call till_reloadPage() to do an immediate reload.
