Ah- good, bug and not my own insanity. Thanks for the response. I will disable when doing remote tomfoolery for the time being.
I'm aware of this bug and we'll try to fix it. For now, you can get chains and graphs to show up by setting Developer`$DisableInteractivity = True. You can put this in your init.m if you want... Of course, they will be missing interactivity!
