Java browser plugin Broken on one login only

[Jim Duda]

I have sun java jre 6.03 installed on my computer.

The libjavaplugin fails to work on one login only, it works for others.

I cannot figure out what is different about the one login.

In firefox, both java and javascript are enabled.

Attempting to go here:
http://www.java.com/en/download/installed.jsp

Allows the applet to load and display info for all logins but one.

It must be some permission issue or something in a .* file in the user 
login.

Any ideas?  I'm stumped.
