Disable changing owner of ticket

[cbravo]

What I currently have is the following configuration. When a client opens a new ticket it goes into a queue. On that queue I have a supervisor and x amount of agents. I have stablished the group permissions of the supervisor to R/W and the agents permissions to read, create, add note, and change priority. The problem I'm having is that when users try to close the ticket or answer they get a "you don't have write access to this ticket". Anyone has any ideas as to how could I solve this? I't doesn't matter if I have to do some programming, just point me to the files I would have to modify to get it to work.

p.d. I'm using ubuntu server 10.04 with otrs 3.0.8

Thank you,

the agents will need rw permissions for working. You can disable the onwer link for them via ACL (have a look at faq.otrs.org for them)
