We have several existing large documents that are part of a book and we are unable to change default settings for stroke and fill. Whatever we try as soon as we draw an object the line and fill revert back to the same setting of stroke weight: 0, color: 0, swatch: none. We can create and save a new document and then go back in and make default changes and it sticks, so we have some knowledge of how to do this. Any help will be appreciated. Thank you! (CS5.5 7.5.3.)
Don't work with books much, but it occurs to me that Graphic Styles are one of the options that can get synchronized across Books. Try changing those Graphic Styles in your Master document and synchronize settings across the book. (Try this on a copy of your Book, since I don't know what other consequences your Book might suffer.)
You got me pointed in the right direction Tom and issue resolved. Thank you!
