Netscape also doesn\'t understand IFRAMES.<P>Because of this, they haven\'t been able to do much with text inside an HTML page unless they use applets, which take totally too long to load.<P>This script changes all of that. This will allow the Web Master to place scrolling text inside the HTML document, using JavaScript only and creating writeDocuments using DIVs<P>To see how this works, simply place your mouse over the UP or DOWN words at the bottom of this text block.<P>You can also use images for these as well.<P>As you can see, this script will allow you to fool Netscape and thereby, allow your visitors using Netscape to enjoy some interactivity not normally allowed with that browser.<P>This script authored by <a href="mailto:mike_mcgrath@lineone.net">mike_mcgrath@lineone.net</a><P>');
