check the speed of the signals you are giving it, if they are too fast
the motor can not mechanically keep up with them and funny things can   
happen.  I realize that too fast for a stepper is quite, fast but I had
a similar problem with running them too fast and if I bumped the stepper, 
or gave it a push, it would start running backwards.  Anyways, just a
thought.
