I love iTunes as a music library and to manage my iPod but it is driving me mad that Apple hasn't bestirred itself to produce a version of it that plays nicely with Vista. The latest version is supposed to be Vista-friendly, but it's very flaky - I know Apple and Microsoft are never going to be the best of friends but this is really annoying me.
I'm glad you guys are not having problems - maybe I'm just unlucky. Sometimes I get a black hole on the monitor where the iTunes window should be: in other words, it doesn't finish loading; and syncing my iPod is very hit and miss. I've tried reinstalling iTunes and it continues to be flaky.
