Hello Ben,

I just ran the same experiment with echo and got the new QUERY_STRING
each time I accessed the script.

I will download the kit from today to see if there's
anything I've fixed in my version which didn't get rolled into the
official beta (cause it is a beta) release.

The differences I see with your environment however are as follows:

1) I don't use MFC.

2) I've been using only C and not C++

3) My libraries have been built on VC++ 4.2 and not VC5.
