Any idea will be appriciable. cron does not have a display associated with it, so your gui app will die. check root's mail, by default all output (errors in this case) from the job will be mailed to the user. you could try the following: DISPLAY=:0.0 in the script, but you'll need to do some xhost stuff for each user that may be logged in on the GUI.
