CGIDEV2 help needed

I have a program that seems to react differently than others for some reason 
that I
cannot discern.

I am using CGIDEV2.  This is a fairly simple program that reads a cookie, 
processes
some data, and displays a table of results.

What I get from the browser (both firefox and IE) is the dreaded '500 Internal 
Server
Error'

I turned on the debug mode for CGIDEV2 and stuck a few calls to wrtdebug in the
program.

It appears that the debug file shows everything working the same as the other 
pages I
am already using... E.g., it shows that the WrtSection calls are running and the
various wrtdebug notes are being output and I seem to see a normal page created 
as
far as the notes in the debug file are concerned.

The cookie is being read okay, with correct data.  The program builds the page 
as it
is supposed to be displayed.  The last thing in the debug file is a note on xxx 
bytes
sent to the browser.


Any suggestions as to what to try next?
