I love Battery Bar and this may be nothing to do with it but ...
After I got BB for my Axim, I got a 256 Mb SD card. I started to install a bunch of music onto it when something happened and Explorer showed hundreds - well lots

- of little folder icons on the SD card and BB suddenly showed the SD card as full. At the time this happened the card had about 190 MB left on it. After a soft reset the Axim required a format of the SD card. Thereafter the card would load some stuff but then an error message popped up and the card would not accept any more stuff on it.
Obviously I thought this was a probelm SD card and sent it back.
However the same thing happened with the replacement.
So I did a hard reset and loaded the music onto the SD card BEFORE loading Battery Bar onto the Axim. Now everything is fine - for the moment.
I hate to say this but it does look as if Battery Bar has some sort of problem with SD cards added after BB has been installed. I may be wrong but, as I say, no problems as yet when I install stuff onto the SD card before installing Battery Bar. I suppose the test will be if anything goes wrong when I try to add some more songs onto the SD card.
What do the experts among us think?
