Shut down conflict with f.lux
I'm experiencing a conflict between f.lux and system shutdown.
When I want to shut down my Mac and have f.lux open - most particularly in the evening - I often experience errors where the system hangs and fails to shut down properly.
I say this after some investigation and having determined that the error only occurs when I have f.lux open - when I close the app before shutting down, nothing untoward happens.
Has anyone else encountered this issue?
