Hi Again,
If you are using pure ACSII Text you will not have any issue using an apostrophe.
In order to completely remove any possible hidden code, I copy from MS Word to Notepad. Then from notepad into Moodle, if you check your source code using the <> button or the HTML button.
You will be able to see the source code, I bet you will notice way too much code, <!--if --> with a bunch of other code.
Do you get the 'print complete book' option to work consistently?
-- Yes, running Moodle 1.9.10.
Run this test:
1. Create a new book
2. Create new content just plain old text (No copying from Word)
3. Create several chapters
4. Add some graphics
Then attempt a print test, if it works then the issue is absolutely your content.
My money is still on the hidden code that got carried over from MS Word.
