print margin changes when saving a word 2000 document in word 2003

[William from Jersey]

- Create document in Word 2000
- Printer\Page setup margins (in original doc) is set mainly to 0 for all
- Paragraph property; "Indents and spacing" set to 0 on original document
- All of the text should be shifted to the far left of the page and I save
the doc..
- I open up the document in Word 2003 and do a "save as" of the original
document in word 2003 with a different name.
- Open up the new document in word 2003 and the print margins are set to
1.25 and Paragraphs have new first line and hanging indents showing left
-0.75* and right -1.13*.
- I see paragraphs indented to the right when it was originally flushed left.

Any Ideas on doc issues between word 2000 and word 2003?
