Notinited error

Question

I'm having a Java problem. First some basic info:
* Windows XP Pro, Service pack 1
* Java VM 1.4.2_03
* IE 6.028
* Opera 7.23
* Mozilla 1.6
The applet at http://www.java.com/en/download/help/testvm.jsp (and many others) fail to load with the error "Java applet Notinited" or "Loading Java Applet Failed".
I've tried with IE and Mozilla set as my default browser and not as default. Made no difference. Only Opera works. :( I should alos mention that I have a "direct" connection to the internet, no proxies needed and the Java console is set to use Browser Settings.
I think that covres all the essential information.
Help!
Oh, one more thing. Here's the outpt of the VM log when I run the test above:

I know that Opera 7.23 can include the 1.4.1 JRE from Sun. Just curious, did you install Opera before or after you installed the 1.4.2 JRE? Also if you look into the "About" tab of the Java Plugin in your control panel, what version do you see there?
MB> Well, here's what the Opera helps says. I'm not sure if Opera includes the runtime in the distro or not. IN any case, it seems Opera avoids the plugin which seems to be where the issue lies.
Support for Java in Opera
Platform: Windows 95/98/Me/NT 4.0/2000/XP
Opera 4 beta 4 and later for Windows have embedded Java support. This means we use the Java Runtime Environment (JRE) directly instead of using the plug-in to run Java applets. It is not possible to use the Java plug-in with Opera 4 beta 4 and later.
Opera for other platforms may support Java through the use of a Java plug-in. Please consult the documentation for each platform for information about Opera's Java capabilities.
The runtime environments supported is the "Java Runtime Environment" from Sun version 1.2 and above. This means that those of you who have been running e.g. the 1.1.3 version of the JRE/plug-in will have to install a new version of JRE to run applets.
Since version 1.2, the Java Runtime Environment and the Java Plug-in is the same download and installation.
JRE can be downloaded from:
