First time I've been reported this message!
Did you try suggestions found on the Internet?

Think i found a reason for it, but not really a way to avoid it.
1st crash occurred when i dragged a library item onto my project, 2nd time was panning 3d screen past where the object was, it is only a 10 cm tall ornament, turns out its size was, it's gone now, 236'145, bigger than any sh3d i have ever created.
