Okay - lots of talk about the stylesheet thing and jumping to the end of the book - but it's TIPS and TRICKS - What else have we got?
There is the LOCKED CONTENT thingy - If you get a message Locked Content when trying to open a book check the filename for apostrophe's. If there are any, remove them from the filename and the book should load fine.
AND there is the VIDEO POKER easter egg - press menu - select help - press menu - select help again and now you have a Video Poker game. (not particularly useful, but some people might like it)
