Instant Movement

I move my Hero-Type units instantly instead of ordering them to move. The plus to this is that I can use a WASD style move system and play thier walk animations properly (Instead of having the animation chopped and skippy like when you order the unit to move to its current position + 20). I got everything to work perfectly now except for some reason the animation doesnt play while moving instantly, it just locks in place. I have done this before and the animation always plays normally in a loop.

Is there some limit to the distance or time interval between movements that allows or pauses animations? I've done 'Slide' effects before in this manner and they played thier animations normally.

EDIT: Solved. I just MDL edited the model and swapped the 'Walk' and 'Stand' animations. Now I just have to call the 'Walk' animation when the unit stands still; simple. Thanks anyway.
