I'm using Excel 2007. I don't know when the problem started, but the problem
is continuing to give me trouble.
The problem is that when I resize the window, the document(spread sheet)
doesn't fit the whole area. The increased area is filled with the blank(or
background) color.

The image from the following link should help.

Give me some help.
Sincerely.
