GUI Texture Problem

I'm trying to make a health bar but whenever I add GUI texture it shows up in both my scene and game view windows when it should only be visible in my game view. Then when I play my game it exits out and lags after 2 seconds. What is wrong?

In the scene view window there is a button that looks like a mountain. If you click on that it will stop showing the gui texture in the scene view window.

Hope this helps.
