Rotating busy cursor

I can't get a continuous rotation X O

I've been trying to make the Range icon from rs into a busy cursor that rotates, but whenever it reaches the last spin it kind of jumps to the upper left a little bit

I've been putting four of the same picture into the image effects toolbar and rotating each picture so it makes a complete spin, dunno if thats the right way to do it but thats what i've been messing with

if someone could help me out i'd be grateful d[o.O]P
