Sorry for late answering (different tome zones) i'll try it after my phone gets charged... something unexpected happened today, it's noon over here and the batt is DEAD... never had this happening before.
Something got stuck in my memory locking the cpu at 100%

EDIT: tried to run visudo and although "nothing happened", I got myself a nice running app called "vi" that was using my cpu 90-100%. The battery lasted 8 hours this way.

Sorry for the of topic.
