Checkers_03

Question

Thanks for Save() and Load() methods. They work good but when I save somethink and Load it, it is loaded after press some key... and How would you do method StepBack ?? I didnt tell u before because I dont know about it:D ok so I will just do Binary seialization, and could I later do also Events?? because it all will be also for Windows Form. Can you tell me about some good tutorial for Windows Form after which I ll be able to remake dll also for WF?? And what about exceptions??. The rest I wont do.Below is whole code. You already can play checker, I just must finish a couple of details. THX!
