Tally Ho, there were also people on the Big Fish Fans page experiencing the same thing with this game, namely a black screen with audio. Various Do/Domini Games have presented players with this problem over the last few years and I am surprised that they have not fixed this by now. Oldbroad and TLC both experience this with some of their games. On the surface this sounds like a video card/video driver specific issue, but of course I can't say this with certainty. It's annoying, for sure. The solution at this point is probably to have two different computers with different system specs and different video cards, but of course it's not always feasible to have this kind of set-up. It's this kind of thing, though, that has always prompted me to try to have two computers around.

I just googled "Domini games black screen with audio" and was shown a number of what sounded like good suggestions to troubleshoot/fix this issue. It might be worth taking a look if you are ever in the mood.
