That is one of the problem w/ non-tournament tables. The quality control is generally terrible. Short of swapping the men I don't know know what to tell you. Even that may not do the trick. If you are really feeling crazy I guess you could try to add more weight to the mens heads but that would likely be more trouble than it's worth. FYI many here, myself included, will tell you to hurry up and return it/sell it and buy a quality table. If you care enough about the men not staying in place, you may actually care enough to learn how to play tournaments some day...
