ICal 3.0.7 not working

Question

Having done the update to OS 10.5.7 I discovered the same issue I had in a previous update (perhaps to 10.5.6? Can't recall exactly), that being that iCal does nothing. That is to say, it starts up but never loads any calendars. Upon trying to Quit iCal, it never quits. It does not 'hang' (Bringing up the Force Quit window does not show any 'not responding', nor does Activity Monitor give any clue that anything is wrong.), it simply just never quits.
To try and get my calendars back I first tried a 'Reset' from MobileMe, then a Restore from Time Machine. In both cases, nothing. On restarting iCal, no calendars.
I then removed the iCal plist file, which also did nothing.
Having been down this path before, and having spent considerable time mucking about last time it occurred, I did not try anything else but instead went straight to:
The solution, as it was last time this occurred, was to use Time Machine to Restore iCal vers. 3.0.2, which continues to work perfectly.
Any one else seen this behavior or have any ideas?
**Note in my specs I state 'Other OS', that is only because the Discussions page does not yet recognize 10.5.7**

Answer 1

William,
No, iCal is dead across the board for all users.
That indicates a system reinstallation of some type will be the only way to correct your problem.
As to the problem 'having been introduced by the Time Machine retrograde...', au contraire. It is only by using Time Machine that I've been able to get iCal working, albeit not with the current version.
Perhaps I could have used better semantics than "introduced by the Time Machine retrograde," but the fact remains that if you are using an older version of iCal your system is not properly updated. Although I may not able to reconstruct the versions, or all of the improvements that iCal has gone through since 3.0.2, this short summary describes iCal changes described by Apple in these Updates:
OS X 10.5.7 iCal
▪ Improves overall reliability with CalDav.
▪ Improves reliability when automatically syncing with MobileMe.
OS X 10.5.5 iCal
▪ Updates iCal to more accurately handle repeating events.
▪ Improves performance when choosing meeting attendees.
▪ Resolves an issue in which the "Refresh All" option may be dimmed ("grayed out") in the contextual menu for certain calendars.
▪ Fixes issues with read-only calendars.
▪ Addresses an issue that prevents an invitee from moving an event to a different calendar.
▪ Resolves an issue with syncing published calendars.
The choice to remain with 3.0.2, or attempt further Updates remains yours.
