Movement Pause

I have a guy that is in Flash5 that uses the directional buttons and the _x+5 or _y+5 to move it aroung the screen fo a game. Now this all works great. BUT!!!!! when it changes directions it pauses for a sec before it starts moving in the new direction. Has anyone any suggestions for solving this. PLEASE HELP!!!!

I think this is just a case of trimming your animtions alittle better (if its possible ) Are you sure you cant make it smother ? :)
