How do I show the mouse and allow the player to click without moving the screen in game?

I have a first person game that is controlled by the mouse, and I have a pause screen that pauses the game and presents the player with buttons to keep playing, restart, or go to the main menu. But right now when I pause you can still look around the game area with the mouse and you can’t click any of the buttons since the mouse is still being used for where to look. How can I fix this so that the player can see the mouse and use it to click the buttons. Here’s my UI code for pause:

public class UIManager : MonoBehaviour {

	GameObject[] pauseObjects;

	// Use this for initialization
	void Start () {
		Time.timeScale = 1;
		pauseObjects = GameObject.FindGameObjectsWithTag("ShowOnPause");
		hidePaused();
	}

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

		//uses the p button to pause and unpause the game
		if(Input.GetKeyDown(KeyCode.P))
		{
			if(Time.timeScale == 1)
			{
				Time.timeScale = 0;
				showPaused();
			} else if (Time.timeScale == 0){
				Debug.Log ("high");
				Time.timeScale = 1;
				hidePaused();
			}
		}
	}


	//Reloads the Level
	public void Reload(){
		Application.LoadLevel(Application.loadedLevel);
	}

	//controls the pausing of the scene
	public void pauseControl(){
		if(Time.timeScale == 1)
		{
			Time.timeScale = 0;
			showPaused();
		} else if (Time.timeScale == 0){
			Time.timeScale = 1;
			hidePaused();
		}
	}

	//shows objects with ShowOnPause tag
	public void showPaused(){
		foreach(GameObject g in pauseObjects){
			g.SetActive(true);
		}
	}

	//hides objects with ShowOnPause tag
	public void hidePaused(){
		foreach(GameObject g in pauseObjects){
			g.SetActive(false);
		}
	}

	//loads inputted level
	public void LoadLevel(string level){
		Application.LoadLevel(level);
	}
}

You could add a flag to ignore the mouse movement while the menu is open. For the not clicking part, it sounds that your canvas is missing a GraphicsRaycaster.
