Hello Phil,

This is an interesting answer.  I'll try the various steps outlined in the M
icrosoft Website and let you know.

However, I have two questions for you:
1. Does your answer account for the fact that this computer and browser (XP 
with Internet Explorer 6.0) works fine when I access other LAS sites that ar
e online?
2. Does your answer account for the information I listed below, especially t
he items from the Apache access_log that show that in the case of the local/
Mozilla client there was a GET /las-bin / followed by a GET /las-output.  Bu
t in the case of this XP/IE system there were two identical GET /las-bin/,  
without any GET /las-output?

Thank you,

Ben
