This feels more like a Super User question than Graphic Design, but I figure someone here will be more likely to know the answer.
Using InDesign 5, I have a "book" collection that I use to keep a bunch of files in one place. Apparently at some point I opened up and modified two of the files apart from the book file, yielding this little warning:
My question is, how do I get rid of the warning, short of removing the file from the book and reinserting it? I figured there has to be a better way. I would have assumed that opening the file from the book, editing, and saving would have reset it, but that hasn't been the case.
