I have not had what I described above. Here the Editor freezes, goes whitish, and most often I have to close it myself with Ctr Alt Del.
As to beta testing, we have wrung the program inside and out, and the freezing problem has been reported.
I count that as crashing too, but mine just locked up a few times completely and then shut down on me. I've had the freeze with the whitish screen a few times too, sometimes it comes back, sometimes I have to shut it down manually.
