Hello, Unfortunately, my Leopard upgrade was a messy one. Without going into details, I had to do a lot of hacking together of old files into the new system and changing a lot of permissions by hand based on best guesses. As it stands, iCal functions normally enough, except I can't change anything. That is, I cannot add, edit, or remove events, to dos, or anything. It's not that they're read-only, just that adding an event isn't reflected in the iCal widget and closing then reopening iCal shows none of the changes were saved. So far I've tried moving ~/Library/Calendars, ~/Library/Application Support/iCal, ~/Library/Caches/Metadata/iCal, and four plist files from ~/Library/Preferences. The preferences clearly reset and so did the calendars (all looked like a first-time setup), but the problem of iCal not saving changes remains. Any thoughts? I'd prefer a fix that doesn't involve a fresh Leopard installation. Thanks a bunch.
