Saving addresses is a function of your browser, not the particular computer you're using. If you're still using Internet Explorer, for instance, after you've entered the address once it should "pop up" any later time you enter the first letter or two. It can't remember something you haven't entered on that computer before, of course. If you have entered it once, though, and your browser is not remembering it, someone may have set up your machine so that it automatically wipes browser history whenever it shuts down. Find and click on the "tools" icon and check the browser history section to see what it shows.
