I used to (and still do) like this game in Vista, so I thought I would try to get it to work on Windows 7. However, I have had no luck, and I don't think that it is possible as I tried everything that I could think of. It is possible that it might be in the RC version of Windows 7 or even the final retail version, but we will have to wait and see. After all, the Internet games, including Backgammon, have made a comeback in Windows 7 after being absent in Vista.
In the meantime, I will have another look at this to see if there is a way, and, if there is, I shall post back here.
