Hi McNeel
So I’ve just had Rhino crash in the weirdest way. I had 1 R6 instance and 1 R7 Beta (latest - just updated this morning) running. I was doing something menial in R6, R7 was in the background with some little Sub-D doodle (not a saved file). R6 suddenly just went “poof”, disappeared and (this is where it gets weird!) took R7 with it. I can’t recall the last time I had one Rhino instance kill another… I’m not even sure if it has ever happened to me before. No crash report, but I’ll see if I can repeat it. Sysinfo below - yes, there’s probably an update for the graphics card… I’ll get right on it

Edit: Yes, I forgot the sysinfo…
