So basically with or without the iPhone plugged in, when I click on iCal to start the program, it bounces in the dock for a second and dissappears. I don't believe I ever deleted the program. I read on the Apple site that people that had this problem had to double check to make sure a certain font was enabled on there computer so the program does not quit. Well, i checked into that and still no luck. I re-installed the software disc and still nothing. Any help would be much appreciated....I want to use iPhone calendar!
