If your issue resulted from the same bug, it's unbelievable that Apple has let it recur in Lion.
Thanks for the links, jsd2.
The experiences that other users have had match mine exactly, using Lion. At least I know I'm not the only one to have seen this problem, but I'm still in a world of hurt.
I have a back up of my home folder which is about one month old (using Backup3 application) so i am hoping this will get me back on track, but before I re-install Lion and restore my backup I will visit the Genius Bar to see what they can do.
Unless there are any other ideas?
It's October, and this happened to me TWICE over the last 2 weeks. Has Apple owned up to this yet?
I wouldn't know, but when I saw the Genius at the Genius Bar he was very apologetic and promised to escalate it to Apple software engineers. I've not heard anything since.
