Thanks to all those who responded to my less problem.  The 'u' flag resolved
the problem.  (And I've added a few other flags to the LESS environment
variable to 'pretty' things up.)  Thanks also to Glen Walker of Edmonton Canada
as well.  I have quoted his email message below for anyone else interested.
Seems there is a fix to the program itself that will correct this problem too.
I haven't tried it yet, but I will soon.

Well, maybe this will make a difference for someone else as well.  Thanks again
for all the input.  See you on the net!
