Make it possible to assign ticket to other user at ticket creation

Hey,

I'm having problems assigning tickets. So far I have created 3 clients and 6 users on the system. I can create tickets fine but when I try to assign a ticket to another user I only get the name of the current user in the dropdown list.

In the jobtrack module section of the permissions I have checked off "can assign tickets to other users" for the right users. Even when I log in as the super administrator I can't assign tickets to individual users just to the admin.

Is there something obvious I'm missing?

Thanks
