Hi! After I (unsuccessfully) upgraded to 10.5.5, iCal started acting strangely regarding the birthdays calendar. At first, it displayed all of them the same day (today). After I restarted and disabled-then-enabled the calendar, I no longer had the bug, but now iCal doesn't display a few birthdays. No matter what I do, they won't display. Any idea how I can fix this? I just reinstalled my OS and the bug is still present. Thank you!
