While In Word 2000

You may have the View in Full Screen mode.

Try going to View and clicking on "Full Screen"

Hope that helped the problem.

Thanks for your response, but I failed to mention in the question, that the DOCUMENT itself does not have these features. So that I can shrink the document or expand it. However Word 2000 does. When you look at the screen you should see 2 sets ofthese symbols in the top right hand corner. One set below the other.
The bottom set of symbols only shows up with an (X) which allows me to only close the document.

I had this same problem in Word 97, and uninstalling and reinstalling Office seemed to fix this problem for me.

I hope this works for you!

Nothing?s wrong, this is how Word 2000 works. It's called Single Document Interface- SDI.
If you'll notice Word places a separate icon on the taskbar for every doc you open. You can Alt+Tab between docs and arrange windows as if they were separate apps.If you have two documents open clicking on the Word Restore button shrinks that document.
Word 2002 allows you to turn this off. 2000 does not.

I have ran into this problem. There is a way to turn it off but you have to do it through the registry. Basically, you have to reset Word to it's orginal setup. Follow the steps below.

To rename the Data key, follow these steps:
Quit all Windows applications.

On the Windows Start menu, click Run.

In the Open box, type regedit, and then click OK.

Locate the following key by double-clicking the appropriate folders:

HKEY_CURRENT_USER\Software\Microsoft\Office\9.0\Word\Data
With the Data folder selected, click Rename on the Edit menu.

Type a new name for the Data folder (for example, type OldData) and then press ENTER.
On the Registry menu, click Exit to close the Registry Editor and restart Word normally (without using the /a switch).
