Can't Eject Ipod?

Heey

I have a 30GB fifth generation Ipod, I used to be able to eject it just fine it just started happening recently, after I updated it, like 2 days ago, which included Safari and a newer version of Quick Time... but when I click the eject button in iTiunes the message appears "Can't eject ipod because some files on the ipod are in use with other applications" I have synced it and everything. I even turned off my computer multiple times, and when I reconnect it the same thing happens. Also when I close iTunes, and click the remove hardware icon on the task bar it ejects just fine. I know it isn't a big problem, since I can eject anyways but it was bugging me anyways. Is there something wrong with iTunes or is there actually a file being used? If so... how can you find out which is being used?

Thanks

First try restoring the ipod on itunes, and see if after the restore it keeps having the issue,

 

I solved it! yay! supposedly quicktime was hogging my files... so I disabled everything quicktime was assigned too and it worked! I love playing around my computer =D
