problems showing full-sized page

[Guest]

When i open explorer i can't see the full-sized page. There's always on the
top of the page a rectangle of the last things i visit that isn't on internet
(like Word, Msn, Excel, etc.) How can i get it back to normal and make it
take the full screen of my computer?
