XNA - Scrolling background problem

Question

Hi!
I'm making a C# XNA Game in Visual Studio 2010 and I've got a problem. My scrolling background does not appear all the time, only in the beginning. Here is my code in the background class:
class BackgroundGameScreen
public Texture2D texture;
public Rectangle rectangle;
public void Draw(SpriteBatch spriteBatch)
spriteBatch.Draw(texture, rectangle, Color.White);
class Scrolling : BackgroundGameScreen
public Scrolling(Texture2D newTexture, Rectangle newRectangle)
texture = newTexture;
rectangle = newRectangle;
public void Update()
rectangle.Y += 3;
Here is my code in the Game1 class:
class Game1 : Microsoft.Xna.Framework.Game
//Some other stuff
Scrolling scrolling1;
Scrolling scrolling2;
protected override void LoadContent()
//Some other stuff
scrolling1 = new Scrolling(Content.Load<Texture2D> ("AirplaneGameScreen"), new Rectangle(0, 0, 700, 630));
scrolling2 = new Scrolling(Content.Load<Texture2D>("AirplaneGameScreen1"), new Rectangle(0, -630, 700, 630));
protected override void Update(GameTime gameTime)
//Some other stuff
if (scrolling1.rectangle.Y + scrolling1.texture.Height <= 0)
scrolling1.rectangle.Y = scrolling2.rectangle.Y + scrolling2.texture.Height;
if (scrolling2.rectangle.Y + scrolling2.texture.Height <= 0)
scrolling2.rectangle.Y = scrolling1.rectangle.Y + scrolling1.texture.Height;
scrolling1.Update();
scrolling2.Update();
protected override void Draw(SpriteBatch spriteBatch)
//Some other stuff like spriteBatch.Draw(...)
scrolling1.Draw(spriteBatch);
scrolling2.Draw(spriteBatch);
I'm glad for all help I can get! :)

Hi friend,
Like your title mentioned, your case related to XNA. I am afraid this is out of our support. You can consider posting it in XNA forum for more efficient responses. This is the link
