I've updgraded all my Macs to Lion and recently bought a new MBA. On the MBA, iCal alerts are not working. I tried deleting the plist files but no luck. iCal alerts work on my other Lion Macs. Anybody else have this problem?
Yeah, it's weird. It's kind of random. I've also noted that sometimes with I close iCal (not Quit, but just close), the app icon in the dock loses its little highlighted dot.
