When creating an audio book, thre's nothing to stop the user using relatively long book titles, such as "A short history of nearly everything by Bill Bryson", but the player on the phone just trucates long titles.
S60 has the ability to scroll lines of text that won't fit on the screen, so that the whole line can be read.
It would be a lot neater if the Audiobook player could do this,
- or alternatively, limit titles in the Manager app to lengths that the player can display (but I guess this latter may not work as different phones have different screen sizes/resolutions).
