When I click on my name button in the upper right hand corner of the screen and select "Developer Console", I only see the Logs, View State, Progress and Problems tabs.  Does anyone know why this is the case?  I'm marked as an "Admin" within user management, we also have the professional edition of Salesforce.com.
