Clip jam turns on when usb is pluged in for charging

Trust me, I have downloaded, printed and read the entirer manual.  But this morning I made an interesting discovery.  When I plug the CJ in to my computer it will go into the charging mode and doesn’t boot up.  Then I took the player in the off position and plugged it into the many wall chargers we all have and the CJ immediately booted up into the music play mode.  Sure I can pause it and it does charge but it does not go into the “charge mode” as it does on the computer.  Interesting and I gather just a quirk of the player.  

So I guess my question is does anyone else have this issue?  The player plays music as advertised and I like the quality.  I just have this quirk that it won’t charge unless it turns itself on.  IF there is any software up date in the future this may be address.  I can only hope.  In the manual it does state this unit can not be overcharged so leaving it plugged in for charging when not in use is okay but you just have to pause the music and walk away I guess.
