I am trying to make a seperate Navigation Tab that is visible only when an administrator is logged in. Any suggestions?

Well, you can bind the visible property of the component to the following expression:`lookup({[System]Client/User/RolesDataSet}, "Administrator", "", 0, 0) = "Administrator"`That will check to see if the current user that is logged in has the Administrator role.

If you are looking to open a window on startup based on who is logged in you can have the following Global Event Startup Script (Client):`if "Administrator" in system.security.getRoles():
	system.nav.openWindow("NavigationWindow")`Hope this helps.
