So how come it's working in firefox?
EDIT:
* ryxdp goes to look in the page source
EDIT 2:
Source says PyroSandMain2, which is a class in the jar (I looked in there, but having no knowledge of java...).
html code:
<p>
<applet code="PyroSandMain2" archive="PS.jar" width="600" height="500">
<param name="width" value="600">
<param name="height" value="500">
</applet>
