This happens with my 160GB Classic as well.//content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gifi have the 80gb ipod classic. when i say locked up the ipod is just "stuck" and won't respond to any input until i hold the menu and center button to reset it. as i posted above, i don't notice when the ipod is locked up -- i'll turn on the x100 and it will give me an error message, then i'll check the ipod and find it stuck
this doesn't happen often, just at annoying times
