I have noticed a serious flaw in 8-ball. After a shot, the balls will stop moving, then in an instant they will change locations. This may happen to one or two balls, or all of them may move to totally different positions. I have sunk a ball and heard it drop only to have it reappear on the table for no reason. This morning my opponent broke the rack and before the balls stopped moving the rack completely reformed and changed to my turn. I have asked many players about these glitches and many have confirmed that they occur in their 8-ball games also, yet I find no discussion in the forum. I am also surprised there is no discussion of the very common general slowdowns (slow appearance of stick for next shot) and jittery movement. I am a paying customer. Chris Duffy Carbondale, IL
