This has been happening for about two months now. I've got the latest version, uninstalled and reinstalled and turned off automatic downloads and yet it still crashes telling me it's had a fault and needs to close. It's driving me nuts! All is silent on Apple's help forums when others have enquired.
Podcasts are the main thing I use my ipod for. We wondered if it's because I have quite a few on there but then what's the point of software that doesn't like having many stored plus I know a lot of people have a tonne of music on their itunes, far more than I would have on my podcasts and they don't seem to have the issue.
I don't have Match or whatever that is, that I've seen mentioned in other 'crashing' posts. If anyone has any ideas, I'd be grateful. The nano is the only Apple thing I have and if this is their idea of keeping customers happy, I'm glad I've no other gadgets of theirs!
