I posted this in another thread, but it's worse than just ical, and am really concerned. I opened ical, and all my cals were gone. i followed a suggestion and tried to copy them back in from the library, but even in the library, they are empty. I reset my computer, hoping that would help (it worked in windows), but when my account loaded, my desktop image was changed. then, i loaded safari, and all my prefs were gone. cookies disappeared - i had to log in again here and elsewhere. mail lost a bunch of old emails. my email accounts disappeared, i had to relist them. i'm not sure what else is gone. what on earth could have happened? while i don't regret switching over, even the worst crashes on my pc were fixed by rebooting - losing all of this is the worst result i've ever had. i've updated everything, and just updated the airport software today, but don't understand how that could have been the problem. i'm using a pb15 1.25 with 10.3.6.
