Sansa Clip+ won't turn off

I had the same problem - and my sansa clip is over a year old.  I think that I did it myself - I was trying to add an audio book disc to the clip and it was refreshing - anyway, after exhausting internet research - and (after I purchased another one from Amazon), I was sitting here and decided to just hold the power button on until my finger got tired - GUESS WHAT, the little flower symbol that was on went out - I then turned it on again - and it began 'refreshing.  Then IT WENT OUT AGAIN - with the little flower symbol.  I shut it off again, by holding that on/off button - then it went out.  I turned it back on and believe it or not, it is now writing the disk that I loaded in this morning.  Go FIgure!  I think I just asked TOO MUCH of the little thing.  There is hope!  Just persevere.  I love my Sansa Clip.
