I am having difficulty with the format controls in a new document produced using Word 365. Clicking on Page layout - Orientation. if I select Portrait the displayed layout is landscape. If I select Landscape, you guessed it, I get a landscape format.

More serious however is the fact that any document I try and print is printed as an A5 document on half the the A4 page. I have tried all the controls I can think off to no avail - margins, columns, paragraph.

I am considering re-installing Word but there must be an easier way.
