I have used a script by David G. Miles to insert a scrollable area onto a webpage. Everything works perfectly when I test it on an IE browser. I can’t get it to work with other browsers like Netscape or Firefox – the area just displays what can fit, it won’t scroll down. Can someone please advise me what I need to do to make this compatible with other browsers? I’ve included the original script exactly as I got it below – this will display correctly in an IE browser. Thanks!
