[Chameleon] Session lock, PHP Warning

Hi Jason,
You were right about the path issue which I managed to soon rectify within
the chameleon.map file. Now the php script works
http://camber.mc.man.ac.uk/script.php . So I went to reload the viewer and
no image but the php log was complaining about the lock file in the session
folder (created in the tmp directory).
When I load the viewer and delete the lock file the images now appear in the
viewer first the keymap then the main map of Canada.
My question is why is the lock file being created? How do I get the lock
file removed so that the images load automatically into the viewer? Is it
possible that some code is incorrect in the session.php file for windows
system as I read a previous thread about this issue, but couldn't find a
solution?
If anyone else has experienced this problem with the chameleon samples on
windows I would really appreciate your advice.
Kind Regards
Gail

Gail,
I suspect path issues. This won't work:
http://camber.mc.man.ac.uk/ms_tmp/111876867135441.gif
But this will:
http://camber.mc.man.ac.uk/tmp/ms_tmp/111876867135441.gif
as the output of your script.php. Do your paths in the Chameleon config
reflect this as well?
