Dear Wendy,

A followup;  I followed these instructions, and am using IBM JVM1.3
(identified in Plugins as Java for Netscape..hmm) further id'd as
"npjava11.dll *12.dll and *32.dll.  Does all that look correct?

Am currently at version 5.11 of Opera.

Are you still using IBM Java?  is a newer version available?  

Remember that accessing, downloading and installing was a real chore.

Thank you for your time.

Warm Regards, Carlos
