You are welcome Ezra, I'm always glad to help where I can.

The one "exception" to all I said yesterday, is that PHP (if I recall
correctly) does not store it's Session variables in memory - but instead
writes the variables to a specially formatted text file on the Server.

It could be a long shot - but maybe you could do something with dynamically
manipulating this file from Witango. I think the folder name which contains
these files has the word "session" in it.

Hope this helps. Cheers......
