I have un-checked all three Automatic Downloads checkboxes in Store prefs, and the store is disabled in Parental prefs. It looks like those checkboxes are magically re-checking themselves the first time a device syncs.
Either "never download anything" or "remember the fucking password and stop asking me" would be acceptable solutions.
only thing i've found is to Store -> Sign Out
I stay signed in and it never asks me for password. But presumably you find staying signed in to be unsatisfactory.
Like I said, "remember the fucking password" would be fine. I don't care if it stays signed in. It doesn't.
I had this problem and fixed it by authorizing the computer again.
While we are bitching, why does your website download a file named 39ECE22AFD4A68BB every time I visit in Safari?
I have no idea. Maybe you have a virus, or a fucked up Flash installation.
Well it only happens at your site. Aha, opening in Firefox reveals: "You have chosen to open 39ECE22AFD4A68BB which is a application/x-shockwave-flash from http://www.youtube.com"
I uninstalled Flash recently, but not the "right way" I guess.
I haven't had this problem in iTunes, but I had an analogous problem in iChat recently (it kept prompting for passwords over and over again) that I did not solve until I blew away the preference .plist files. I never found a good explanation of what was wrong, and it was a bit "nuke it from space", but it did solve it.
I'd suggest moving your .plist files off to the side and seeing if the problem persists. If not, you then get to either reconstruct all your preferences from scratch (painful) or figure out which precise .plist entry is causing the trouble (not worth it, IMHO, but everyone has their tastes.)
You must be mistaken. The folks at Apple are design geniuses.
I've had Mac apps deal poorly with there being a password stored in Keychain for their service which was wrong. For whatever reason they wouldn't replace the old entry with the new one after prompting for it. Deleting the old password entry gets them back on track.
My iTunes was doing this for awhile, but the update they released last week seems to have fixed it.
