[otrs] Queue Access

I have OTRS 2.3.3 with ITSM 1.2 installed on my server, debian if it helps although I installed completely from source. I have several agents with different permissions and queues. I don't wanna give full RW access to several agents because I don't want them to be able to close tickets, however if I don't give them RW they can't see the tickets on my queues or such, just looking for the tickets on the search panel. It is not a preferences thing as I have it configure so that every user has the assigned queues on my queues on their preferences. Could you let me know how to fix this? Is there a configuration option I can change? Thanks in advance, -- Jose Bogarín
