Ok - with the 0.46 desktop version it works sort of. If I view the cam, and William is there, I can click him, and stuff works. If I click anywhere else it goes black and I need to right click my way out.
If I click at any time besides midnight, it goes black and right click does not work, i have to kill the game.
But I got it working. Now if only there was a downloadable 0.47...
