Delay after setting mainTexture

Gday all,

I am having trouble with a quick project I am trying to finish off in the next few hours... It isnt game breaking but it is a bit annoying.

Webplayer: https://dl.dropboxusercontent.com/u/74159983/Frogpad/Frogpad.html

It is a basic boardgame where you play a frog, after you roll, the frog jumps to the next square. I am simulating a jump just by changing textures but for some reason there is a very noticeable (2-3 second) delay between changing the texture and executing the next part of the code. (Immediately evident if you look at webplayer)

The code I am using is:

currentPlayerScript

 function Start () {
     renderer.material.mainTexture = normalFrog;
 }
 
 function Update () {
 
 }
 
 function Jump(){
     renderer.material.mainTexture = jumpingFrog;
 }
 
 
 function Land () {
     renderer.material.mainTexture = normalFrog;
 }
 
 function Splash () {
     renderer.material.mainTexture = splashFrog;
 }
 
 function SetPlayer(){
     isHuman = true;
 }

Key part of movement function

 currentPlayerScript.Jump();
 
 var distCovered = (Time.time - startTime) * moveSpeed;
 var fracJourney = distCovered - distanceToMove;
 
 while (!done){
     distCovered = (Time.time - startTime) * moveSpeed;
     fracJourney = distCovered - distanceToMove;
     currentPlayer.position = Vector3.Lerp(startLocation, moveLocation, fracJourney);
     yield;
     if (fracJourney > 0.99){
         done = true;
         currentPlayerScript.currentSquare = newPos;
         }
 }

Full function in movement script

 function MoveCharacter(i : int){
     turnState = 2;
     
     var newPos = currentPlayerScript.currentSquare + i;
     if (newPos > boardSquares.Count - 1){
         newPos = boardSquares.Count - 1;
         }
     if (newPos < 0){
         newPos = 0;
         }
     
     var moveLocation = boardSquares[newPos].transform.position;
     moveLocation += currentPlayerScript.safetyOffset;
     var distanceToMove = (currentPlayer.position - moveLocation).magnitude;
     var startLocation = currentPlayer.position;
     
     var moveSpeed = 1;
     var startTime = Time.time;
     
     var done = false;
     
     currentPlayerScript.Jump();
     
     var distCovered = (Time.time - startTime) * moveSpeed;
     var fracJourney = distCovered - distanceToMove;
     
     while (!done){
         distCovered = (Time.time - startTime) * moveSpeed;
         fracJourney = distCovered - distanceToMove;
         currentPlayer.position = Vector3.Lerp(startLocation, moveLocation, fracJourney);
         yield;
         if (fracJourney > 0.99){
             done = true;
             currentPlayerScript.currentSquare = newPos;
             }
     }
     
     if (boardSquares[newPos].waterSquare){
         currentPlayerScript.Splash();
         moveMod = -1;
         RunTurn();
     }
     else { 
         currentPlayerScript.Land();
         moveMod = 1;
         EndTurn();
         }
     
     
 }

I have no idea why it is doing this other than maybe a delay with changing the texture, but the actual texture change is instant... it is the delay afterwards which confuses me (I would have thought if there would be a delay, it would be as the texture was changing, not afterwards?)

Any help is greatly appreciated!
