I'm sorry I didn't answered up to now.. Sometimes the threads get lost into the forums

So: if I set a calendar event, and I want to be warned when it is about to happen, I set an alarm, let's say it will be triggered 5 minutes before 12.30.

As soon as the clock switches from 12.24 to 12.25, GPE Calendar will crash. Launch it again and it'll crash again. Launch it a second time and it'll work. That's all.

Bye, Omar
