This, for me, is caused by the weight of the mouse cord itself. The cord is thinner than most mouse cords and not extremely rigid but does weigh enough to pull the mouse. The teflon pads don't help this any at all either. It really doesn't bother me at all.
That, in my opinion, is the cause of the "pull." Sorry I can't help you out more but thats the only thing that I have observed to have cause this. The insane dpi doesnt help either but regardless, it doesn't bother me. You will love this mouse pad.
