Below is a screen shot of what I'm calling "lost shading". By moving pages around, possibly with incorrect shuffling settings, I now have half a page shaded and the other pure white.
I can't drag/expand the shaded side across the spread. I can't copy and paste it from another spread. Something is wrong with the page itself since it resists any approach I've tried.
Thanks for the advice.
Paul
Some pages look like this:
North America
Europe, Middle East and Africa
Asia Pacific
