New Prime, several crashes

[Cristian Arezzini]

Thanks Tim, you wrote "format" but somehow I read "reset". Anyway now I formatted the memory (it took an instant, is that right?) and started from scratch.
I still had a crash. Only one, but I didn't spend much time trying. Again it happened while modifying the same set of equations. I haven't had crashes in other areas, but again I haven't done much else with this new unit...
