Why when we are working with a material of many pages, and all pages have the same measure, and alter the size of each page (in File -> Document Setup), we can no longer generate booklets? I was tested in version CS5 and it worked perfectly in version CS6 gives error:
"The active document uses multiple pages sizes. Booklet Print works only with documents That use consistent page size."
I've checked all pages and it all have identical size between them.
Take a test.
Open a new file with multiple pages. Try to create a booklet. Will function properly. After this, go to File -> Size and change the page size of the pages. Now try to create a booklet. Will give error.
I tested in a couple of macs...
