try this:

Code:

---

//scale vector, make it slower
vec_scale(temp,(Scale *time_step)); 

//calculate how many times to rotate when vector is scaled
tmpCounter= Scale  *time_step  ; 

while(counter < tmpCounter)
{
  c_rotate(me, temp, glide);
  counter+=1;
  wait(1);
}

---

edit: if it works now you still should include time_step in your code otherwise the rotation wont be smooth
