MESSAGES & DIALOG BOXES
Normally, when you type in an URL
or click on a
browser will show you the
page you want. Sometimes however, there's a problem.
An URL is like
a phone number; if you don't type it exactly right, you won't get through.
If the browser can't find the URL you typed in, it will usually show you
a list of links to web pages that resemble the URL you typed in.
If there's a link to the web page you want, just click on it. If
not, try typing the URL again.
like telephone numbers, sometimes URLs change. That makes a link
that used to work suddenly stop working. When that happens, you'll
have to find out the new URL.
people who own a web site will go out of business and/or sell their
URL to someone else. When that happens, the old web site vanishes
and/or is replaced by a new one.
sites are so busy, they just can't respond when you try to reach them.
It's like getting a busy signal on the telephone; if you try back later,
you'll probably get through.

might tell you that you are about to send information over an insecure
line, or that you are entering or leaving an encrypted site. It might
tell you that you need different software to view the web site you
want. It might ask permission to download something to your computer.
A dialog box won't go away until you have clicked an answer button.
