Hello André,

I have the same behaviour. However, after some trial, I come to the following 
conclusion: the message sould be understood as: "for 120 minutes you won't 
have to enter the root password again *for the application you have just 
given root rights*, not *for all applications*.

When I tried, I got this behaviour:

open synaptic - asked give root password - ticked the option to keep it - 
enter root password

open gparted- asked give root password

open root terminal- asked give root password

open synaptic- no password asked - closed synaptic

open- no password asked - closed synaptic 


So I think it's not a bug, it's a missunderstanding of the message's meaning 
(or maybe we could ask the message to say "kept for up to 120 minutes for 
this app"

Regards,

Thierry
