The symptoms are as following:
After login to a web portal running Apache/Tomcat and using an email and
password as a source (in which they type in) they are prompted with a
blank page. They then have to refresh the screen to continue on. The then
have to refresh on each new page because of something wrong in viewing
each page.

If we run this from Firefox we do not have the problem. If we remove the
zfd65 agent the problem goes away.

We have the latest client with no netidentity service installed, however
they do have the latest zen65 agent sp1

in the header I find the line for
NovINet: v1.2

can some one tell me how i can disable this function with out removing the
zen agent.
