OnMouseOver 2 Textures are shown over object

[b5-danny]

Hey guys im new to Unity3D and have a little problem

I have a custom MouseTexture for my Game using this Code:

using UnityEngine;
using System.Collections;

public class MausCursor : MonoBehaviour {
public Texture cursorImage;

// Use this for initialization
void Start () {
Screen.showCursor = false;
}

// Update is called once per frame
void Update () {

}

void OnGUI(){
Vector3 mousePos = Input.mousePosition;
Rect pos = new Rect (mousePos.x, Screen.height - mousePos.y, cursorImage.width, cursorImage.height);
GUI.Label (pos, cursorImage);
}
}

And now i wanted to use a Mouseover function - it works ok so far but theres still a little problem

when im not over the object: mouse shows the custom mouse texture
when im over the object: mouse shows custom mouse texture and the “hover texture”

heres the code im using so far on the object:

var myCursor:Texture2D;

var cursorSizeX: int = 32; // set to width of your cursor texture

var cursorSizeY: int = 32; // set to height of your cursor texture

var condition = true;

function OnMouseEnter(){

condition = false;

Screen.showCursor = false;

}

function OnMouseExit(){

condition = true;

Screen.showCursor = false;

}

function OnGUI(){

if(!condition){

GUI.DrawTexture (Rect(Input.mousePosition.x-cursorSizeX + cursorSizeX, (Screen.height-Input.mousePosition.y)-cursorSizeY + cursorSizeY, cursorSizeX, cursorSizeY),myCursor);

}

}
