I was hoping it was an x.0 bug, but no, they haven’t changed it.
Installing iTunes 5.0.1 just now, I was struck by a couple of things.
First, a dialog telling you to quit it appears first. Didn’t the installer just use to quit it for you? Furthermore, the dialog in question doesn’t have the app. icon on it, just plain text and a big gap… and it keeps asking you to quit iTunes, after, um, you’ve quit iTunes. Buggy. Ugh.
Second, you have to agree to the licence twice, firstly when downloading from Software Update, then when you first open the app. That sucks.
Hopefully the app itself will be fine…
