Problemas launching firefox from a script

["startux.org webmaster" <webmaster@xxxxxxxxxxx>]

Hi,

I'm developing a prototype of a multimedia Linux kiosk.

When the kiosk starts, it launches Firefox in fullscreen mode. It's
fine.

Then, i have a script in PERL called every 10 minutes by the cron daemon
to check if the kiosk has connection to the internet or not.
So, i test every 10 minutes the state of the conection.
If the state changes, i want to run Firefox with a different page.

The problem is that if i launch the script from a X terminal, everything
is ok.
When called by the cron daemon i get this error:

"Failed to conect to X server"

I'm running Mandrake 10.0 / WindowMaker / X 4.3.0.1

I sent you my PERL script and my crontab file so that you can evaluate
what's going on.

I've already run "xhost +" and "export DISPLAY=:0.0", but no good :(

Any help would be appreciated.

Thanks in advance.

Warm Regards,
Mário Gamito
