Joe,
You Rock! You gave me just enough hints to help me find the problem. I am
sitting here watching TV on my PC as I type this. I can not thank you
enough.
The problem was 2 things, 1) the old module files were still out there
somewhere and they were the ones being loaded, I searched for them and moved
replaced every one I found with the new ones. 2) Somehow I missed moving 4 of
the module files into the module directories, once I realized that it was
smooth sailing.
Thanks again, and have a good day.
Kent
