Exporting the entire page

I've been jogging along nicely with X4 for a while bit have just hit a problem that I hope is due to me missing something obvious.

Having created a design on an A4 page, how do I export the design and the A4 page to JPEG, please?

Each time I export I get just the design, no the A4 area. I can't find anything in the Help file and, for the first time, the otherwise excellent Unleashed DVD has also drawn a blank.
