Hi Mike, You don't need the beta software to set bookmarks in mp3's. Use 4+6 to set marks, and navigate between them with 4+ 5 for previous mark and 5+6 for next mark. I've had my BP since around April of last year, and it has always had this capability. So this is not something unique to the beta. Enjoy! Regarding the lithium batteries: If you are getting 90% on mp3's, they are probably getting ready to die. Are you still on your first set? I have gone through two sets of lithiums and a couple of sets of NIMH's since you mentioned using your lithium batteries. What brand are you using? Maybe I just use lots more audio than others. (I do use the BP a lot for audible and daisy books.) Angie On Tue, 8 Mar 2005 20:17:06 -0600, Mike Arrigo wrote: >great, once the new software is official, I will try it.
