I waited a long time to upgrade my MacBook to Snow Leopard, mostly because I didn't really need any of the speed increases or other updates, and because I remained concerned about having new bugs in my system. I was always happy with Leopard and never had any issues. I finally did upgrade to SL, and iCal is giving me hell. Its tough to explain the problems that its causing. Basically, the boxes get out of alignment (see attached screenshot), then stuff disappears, sometimes will come back if I click forward a month and then back. If I do this more than one or two times, it just straight up crashes. It is incredibly frustrating. Has anyone else run into similar iCal issues? I feel like a calendar program is one of the more straightforward things Apple has to work on, so I am really surprised that out of everything, this is the biggest upgrade problem I have run into. Thanks in advance for any troubleshooting tips or help of any kind!
