Editor needs sensitivity training! (now a bit "off track")

A couple of months ago, I was prepared to declare the Timetable Editor finally stabilized. Now, I'm glad I kept my mouth shut. Over the past week or so, it has become more and more sensitive, shutting down abruptly for no apparent reason without even passing through an SBHH message. One second I'm editing and the next I'm looking at a dump message, knowing that not even RSC can read the dump-files anymore.
Have any other scenario writers noticed this?
