Clip jam turns on when usb is pluged in for charging

I have tried that too even backing out of the screen of music play to the straight “Music, Settings, Radio, ect” screen.  In my opinion it’s all about seeing the computer or not.  I kind of remember Apple OS had an issue like this some time ago.  It had to be there usb cable AND their charger.  It’s too bad Sandisk doesn’t have a phone support or live “chat” to ask these questions or rais this issue with them or their engineers,.  Again, in my very humble opinion the Sandisk player is the best I have used, even better and easier to use them my old “IPod”.  I have an old Sandisk Sansa 250 that is my very best and most reliable mp3 player but I have out grown it’s 2gig memory.  I wish I could buy that player in a 4 gig and I would be happy but the Clip Jam is just as good a player and the volumn and sound quality can’t be beat.  Just have this one issue that I can live with if there is no fix.
