THANK YOU very much.

We found that our path had C:\Perl\bin\ (with a trailing slash). We updated the path environment variable to be C:\Perl\bin without the path and it started to work.

HOWEVER, being the curious person I am, I switched my path environment variable back to C:\Perl\bin\, lo and behold my script still worked. I was expecting it to fail again.

Any thoughts on this one, or should I just leave well enough alone?
