this question is morphing, but here is the answer to your comment. This will force the user to click each time they want to fire...

var blockPrefab:Transform; var targetT:Transform;

function Start ()
{
    GameObject go = GameObject.Find ("Stickyblock");

 // cache the transform component, for performance
 targetT = go.transform;

function Update ()
{
    var canFire = 1;
    if(Input.GetButtonDown("Fire1")) 
    { 
        if (canFire == 1}
        {
            var block = Instantiate(blockPrefab, GameObject.Find("Cube").transform.position, Quaternion.identity);

         var sticky = Instantiate(Stickyblock, targetT.position, Quaternion.identity); 
         canFire = 0;
 } 
 else if (Input.GetButtonUp ("Fire1")) 
 {
     canFire = 1;
 }

Hey man, why are you using find to set the transform position? Not got Unity fired up atm but Stickyblock, GameObject.Find("Stickyblock")

looks like it will loop?
