Internet explorer hates my applet

Ok, basically:
I made a small game.
It works fine in firefox.
It works in internet explorer about 5% of the time. No reason why it refuses to work the rest (it says Wheel.class not found or Init.class not found or something, i cant find the exact error because its working just now.)

I have no idea whats going on, and its beginning to drive me insane.

Can anyone shed any light on whats wrong?

The game is at
http://www.actionjesus.pwp.blueyonder.co.uk/other/wheel.htm
the source code is at
http://www.actionjesus.pwp.blueyonder.co.uk/Wheel.java

many thanks for any help.

the java console at IE 6 says:
java.lang.UnsupportedClassVersionError: Wheel (Unsupported major.minor version 49.0)
      at java.lang.ClassLoader.defineClass0(Native Method)
      at java.lang.ClassLoader.defineClass(Unknown Source)
      at java.security.SecureClassLoader.defineClass(Unknown Source)
      at sun.applet.AppletClassLoader.findClass(Unknown Source)
      at java.lang.ClassLoader.loadClass(Unknown Source)
      at sun.applet.AppletClassLoader.loadClass(Unknown Source)
      at java.lang.ClassLoader.loadClass(Unknown Source)
      at sun.applet.AppletClassLoader.loadCode(Unknown Source)
      at sun.applet.AppletPanel.createApplet(Unknown Source)
      at sun.plugin.AppletViewer.createApplet(Unknown Source)
      at sun.applet.AppletPanel.runLoader(Unknown Source)
      at sun.applet.AppletPanel.run(Unknown Source)
      at java.lang.Thread.run(Unknown Source)

That typically means that the applet was compiled by an older version from the JVM that
runs on my local machine (1.4.2_03)

try recompiling it on a newer version.

Did you install SUN's JAVA (JRE) on the target machine?

The standard JVM from Microsoft is a bit obsolete ...

It is running perfectly at my end. My IE 6.0 uses  jre 5
As suggested by sciuriware try installing new jre to your IE

If your applet is not actually using any features of 1.5, recompile it to as low a version as possible using

javac -target 1.2 <other args> YourApplet.java

or hardly anyone will be able to see it

That seems to have done the job quite nicely.
I was running an older version (i think). I installed version 5 and everythings running fine now.

Not sure why firefox would handle it so well but explorer died. Oh well.

Bulk of points to sciuriware, some to sudhakar for assisting.

Thanks all.

Maybe because the IE in question has < 1.5 runtime

Yes, missed that by seconds. Never mind ;-)
