[Jose Mourinho]

I have an A4 doc with large white margin on the right, which leaves text
section 'offset' to left. I cannot see how to change this.

The Horizontal Ruler looks strange and doesn't cover the full width of the
selected A4 paper: the ruler begins on far right in line with right side of
paper, a 'blued-out' margin is as defined in Page Set-up, Edit-able section
follows, then left margin and then the ruler stops at 7.2" on right, but the
paper continues to full 8.27" A4 width. i.e over an inch of space
(un-editable) remains on the right.

I cannot see how to change this in Page Set-up or Tools/etc. New docs do not
show this, so is particular to this file - (might have been editted for a
while in word 2007 by a colleague, but is saved as 2003).
