Thanks to Andrew and Steve for very quick and easy to follow
instructions...
I was sure that I did it differently in the past which seemed more
complicated than what has been suggested and worked this time...
The instructions were:
to be able to get the A4 paper default to "stick" by setting it from
within the Format > Document menu.
(click on Page setup, pick the settings you want, click on OK, then
click on the "Default..." button to lock it in)
For those who know easy.... it would be easier if this was in the
basic page set up OR when you register office as an Australian user
they know were are not using the US paper format...
Thanks again for your prompt attention to my problem,
Phil
