This has happened to me three times in the last month, using honeybee (and ladybug? cant remember) components.
What happens is that I see the simulation windows pop up and then bam - windows goes into its normal shut down behaviour displaying a shut down screen.
I always save one core for stability and simulate with 7 instead of 8 cores. (Xeon E3-1505M @ 3GHz)
What could be causing this?
