Use recording but not lose my place


I have a new Clip.  I currently use it to listen to audio books that are all one huge file.  I also carry a digital recorder.  I would prefer to use the recorder on the Clip, but when I use it I lose my place in my book which means I have to remember the place (lousy memory)! 

The same happens if I am listening to a book and want to switch to music. 


Do you have the latest firmware loaded?  Awhile back, bookmarking was added for audiobooks and podcasts.  For it to work (I think I have this right, but others correct me if I am wrong), the files should be tagged as audiobook or podcast, or should be filed on the Clip under those folders.
