Demo crash issue

Hello all,

I'm evaluating the current demo for purchase, and so far it works beautifully on my system with one exception:  When I go to File -> Preferences and try to change my midi input device, the demo crashes. 

Is this a known problem?  Is it peculiar to the demo, or is it shared by the full version?

Could it have anything to do with the fact that I have midi loopback devices in my midi device list?
