I get error when I click Purchse module or users in settings... It says uncaught error 

i.e. 

Uncaught TypeError: Cannot read property 'name' of undefined

http://localhost:8069/web/webclient/js?db=openerp:3724

But

Problem gets solved if i log in from opengsvc user account..but if I log in from my own computer user account problem sustains why it happens?

Why it allows only opengsvc account? How Can I access odoo from my own computer user account?

Thanks
