G4 Java question

[Ron Michael]

Hello G4 experts! Apple has taken control of my Mac G4 1.25ghz with Jaguar.
I just updated my Jaguar to Java l.4.1 as suggested by Apple's Software
Update. Now, I'm having various Java errors including
Link:javascript:void(0) Real Audio which I use to listen to various audio
channels. It worked prior to the update.
I've downgraded my IE Explorer from 5.2.3 to 5.2.2 thinking that might help.
No. Downgraded to Java l.3.1 to see if that would help. No. Also getting
JavaScript alert messages in the latest Navigator and Safari. When I open
the MIME setting helpers in IE Preferences the Java area looks like a bunch
of jipperish. Some of the settings are:
1.1 Specific Java Applets/.javaapplet1.1 and so on with these versions.
Under MIME type in File Helper settings in Preferences.
1.1.1
1.1.2
1.1.3
1.2
1.2.1
1.2.2
1.3
1.3.1
Also how to I stop Preview Apple application from opening my .jpg files by
default. I want to use QuickTime Viewer. Have tried changing this in IE File
Helper settings with no success.
Sorry for the long post. I've worked three days on this with no success.
