Dreamweaver ?

I have a question reguarding dreamweavers main page you build code/design on. Near the bottom left of the screen, it shows a little tab that says the name of the page you saved the page as, or if you didn't save it yet or rename it it says untitled 1, and if you open a new page you get untitled 2, or what ever you name it as. This is on the bottom left of the screen, not the top part. On my computer it shows the tabs, but my friends computer doesn't and he wants to turn it on. I have not been able to find out how to either enable it or disable it. Has anyone here? It is the same at school, some computers have it, and some don't.
any help would be greatly appreciated.

Thank you,
