If you're on Telus, try downloading the the update which was released yesterday (10.0.10.85). Details can be found here: http://blogs.blackberry.com/2013/03/blackberry-10-

I've had the same problem.
I find I have to enter basic information (say a name or location), and then "save" my entry without making any time or date or notification changes. If I touch any of those, it boots me out of the program. After saving, then I have been able to re-open the entry, select to edit it, and input the rest of my information. Cumbersome and stupid, but manageable. I'm looking forward to a bug fix on this one!
