Have read all the blogs and have noticed that the folks not being able to save have said that they are using Vista. I purchased the game today and am running it on windows xp. The first time I opted to save it did it automatically and then the second time didn't save at all. I have tried a few times and no go. Like others I don't have time to finish the puzzle in one sitting so its frustrating to come back and find you are back to square one. Has anyone found a solution to this problem. If so I hope that you can help me. cheers to BF for making this game available.
