Word Document View

Normally when I set up an document in word and I adjust the margins, I am
able to see the page layout as it will be printed. Now when I set up a Word
document, and I set up the top and bottom margins, no matter what I set them
to, it appears on the screen with no top and bottom margins. It just
'shrinks the page'. (If the paper size is 8x10 and I change the top and
bottom margins to 1.5 inches, for a total of 3 inches, the paper appears to
be 8x7, the 'margin space' disappears.) When I adjust the left and right
margins, the margins show in relation to the document, that is, the document
still appears to be 8 inches wide, but a 1 inch margin shows on the left and
right of the document. did I somehow damage my normal.dot? If so, how do I
get it back? How can I fix this?

Thanks
