Hi Anthony,
Not sure how much help this will be, but...
It's some time since I stopped using MS word, in favour of Open Office. But I seem to recall that, at the bottom left of the Word window, you have a selection of three or four 'buttons', that alter the 'view' of your document. I don't have these in OO, but I always used the, I think, 'print view' option. this keeps the page in W.Y.S.I.W.Y.G. format. 'Normal' view gives you one huge page, on which, though your text wraps normally, you can move a seemingly infinite distance to the right of your text, requiring,as you say, clicking on the page shift to get back. Maybe try hitting these buttons, see what happens?
Of course, there's always a good chance I'm talking gibberish... :-)
Dave.
