My applet doesn't work on Linux

Question

I've heard from some people working on Linux platform that my applet http://astro.ia.uz.zgora.pl/~nirgal/psren.htm doesn't work even if they have proper JRE plugin installed. The same people can run other applets on other web sites. The applet works good on Windows platform browsers.
Dear Linux users, do you have any ideas about this issue?

Answer 1

Ok, I hope the code of the main applet class will help to solve the problem. Surely there is some bug (because other applets work). But I'm curious why it runs well on Windows at the same time?
package main;
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.border.*;
import java.awt.*;
import java.awt.event.*;
import pulsarek.*;
