Welcome back Redscreen of death

I'm a happy camper in R7 land until today. I tried to drag an calendar entry (my appointment with SQ325) from one day to another. The "meeting" starts in German time and ends Singapore time and is more than 12 hours (I hope they have power sockets in coach by now). And tada, my first redscreen in R7. Didn't had any in the beta (but hadn't an SQ325 appointment then). Interesting fact: the client crashed AFTER succesfully changing the meeting. Everything looked fine afer completion of the consistency check.
