Thanks Steven and Peter:

Additional info - see the attached file for the error message. Also,
after dismissing that message I see a command window with the following
text:

I have two copies of protocol.ini; one at I:\IBMCOM and the other at
I:\IBMCOM\MACS. They are quite different. When editing them with the
default editor (e.exe) should I save as a text file or a command file,
or should I use a different editor?

Yes, the plugin appears to be raising havoc with Mozilla. I have just
now moved the Java plugin files out of my PLUGINS directory.

What happens if you run:

I have the Innotek version on my system (as well as 1.1.8)

[I:\]java -version

Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_01-b06)

It is already there.

There is no route command. Setup.cmd is:
