some java applets don't run

[poppo144]

I am using Fedora 10 Live USB. I have to install open jdk from scratch with the command: yum install openjdk-1.6.0-plugin The java applets in some websites work fine, in my case the rubik cube applet on http://lar5.com/cube But it fails disappointingly on http://www.gokgs.com/applet.jsp

at KGS the java console report this (from Opera browser)

Exception in thread "TimerQueue" Exception in thread "Thread-13" java.lang.NoClassDefFoundError: Could not initialize class org.igoweb.kgs.client.swing.C
	at org.igoweb.kgs.client.swing.KApplet.a(applet:37)
	at Z.start(applet:162)
	at com.opera.AppletPanel.runHandlerThread(AppletPanel.java:478)
	at com.opera.AppletPanel.run(AppletPanel.java:353)
	at java.lang.Thread.run(Thread.java:636)

at 2nd attempt:

Exception in thread "TimerQueue" Exception in thread "Thread-16" java.lang.NoClassDefFoundError: Could not initialize class org.igoweb.kgs.client.swing.C
	at org.igoweb.kgs.client.swing.KApplet.a(applet:37)

	at com.opera.AppletPanel.run(AppletPanel.java:353)
	at java.lang.Thread.run(Thread.java:636)

this is incomprehinsible to me. what can I do to solve the problem?

P.S. both sites look fine to me on a casual look; Opera-9.64-gcc4.shared.qt3 on F10-i686 with Sun Java jre-1.6.0_14 (self-extracting RPM, not recommended).

I eventually find the answer. I need to open only one window and no other tab in order to run the KGS applet. BTW many thanks for your reply.
