Hi Michael,

This bug has been fixed in the most current release of Orca (0.28.0 dev 
454) or later, which you can download from

http://www.orcaware.com/orca/pub/snapshots/

Let me know if this does or does not work for you.

Here's the change log message for this fix:

     Fix a bug with the new volatile processing code where a ? character
     can now appear in the HTML and image filenames when the 'data'
     parameter in an Orca configuration file contains a ? character.
     Filenames containing a ? character can not be download by the
     browser because the web server interprets the ? character as the
     start of a CGI parameter name=value pair query string and removes
     the query portion from the URL when it looks for the file in the
     filesystem and hence does not open() the correct filename.

Regards,
Blair
