I have a problem. Can anyone help?

[Pinky Molebuster]

I am English and I am using the excellent Scrapbook Maxi to promote my new venture , a "Swap 'n Share" arts & crafts club for children here in Mayenne, France. I have nine pages of information OK but the tenth has expanded off screen and I cannot find a way of condensing it. The only clue I can give anyone is in the right hand corner the figure. For 9 pages it is 750x550 whilst the rogue page is 1600x1600

trying fixing the background size. Go in background (like you do when you set an image as a background) but click on size and then set the last page to 750x550.
