In addition of JussiValkonen's message, I want to suggest you firstly define correct menubar form, you can get it from Admin tab -> Roles managment -> Role List, then open decided role and switch to Resources -> Tab, where you should check all tabs that have interfaces to open ticket forms.
This suggestion is based on my own experience, once I have restricted some menubar action from Analyst interface and was confused while Analysts keeping using it, solution was Quick Profile tab that used menubar_qp that I missed when created restrictions.
