Hi manda04, welcome to SAF
Some websites have buggy scripts. What may be happening is that you may have an outdated IE version (tell us what version you are using) or an outdated Java version (or both). Flash plugin may also be needed.
Win98SE should work fine using
IE 6 SP1,
Java Runtime Environment (JRE) 5.0 Update 12, and
Adobe Flash Player.
Make sure you have Java permissions enabled on your Internet options.
Let us know how it goes.
Chris
