The matrices may line up funny if you have a smaller display. Make sure you maximize your screen, and it should show up fine. A 800x600 resolution (not maximized) works fine, 640x480 should also look ok maximized.
I have tested it with many matrices in both browsers (Netscape Navigator and Internet Explorer) with versions 3.0 and 4.0 on Windows 95 and have had no problems. I believe Netscape implemented Java Script in ver. 2.0, so it may work there also.
With statements like these, can you tell this was written a long time ago?
