CGI+execute external program+Apache serveur

Hello :)

My configuration:
Windows XP, Apache server, Cgi Script in PYTHON , CM synergy (an
external program)

1)
I want to start an external program in my python script... It works
when i execute it manually (double click) and the external program
window appear. but when i call it from the server
(http://localhors/cgi-bin/extract_source.py) it goes VERY slowly.....
and failed (=>The page cannot be displayed)

here the program:
cmd= "\\\\path\\ccm start"
sys.stdin.flush()
sys.stdout.flush()
sys.stderr.flush()
stdin, stdout, stderr = os.popen3(cmd) # it only
execute the cmd commande
sys.stdin.flush()
sys.stdout.flush()
sys.stderr.flush()

2)
Showing that it failed, i have tried another approch: starting manually
the external program (and open his windows) then call interactive
command with the external program through the script.
BUT
When i start the program (CM synergy) manually... and then want to
execute commande with my script (like "check out") it shows this
message "Session not found, please run "ccm start" command"

:)
thanks for reading, thanks for your help..i'm desesperate!
