Vista - ipod 3rd gen nano and vista

here is my problem:

here is what my pc states when i try to discconnect:


the ipod cannot be ejected beacuse it contains files that are in use by another application


steps i took
1-safely remove hardware(results no good)
2-ejecting from i tunes(results no good)
3-going into expolre ejecting from there(results no good)
4-shutting down windows(results good, of course the computer is off)
