GUI Tooltip reacts to Mouse and Keyboard in Web Player? Why?

When including this simple Button Tooltip

function OnGUI () { GUI.Button (Rect (0, 0, 100, 20), GUIContent ("Game Tips", "- To Toggle through background Music Press 'P'\n\n- Control your Jumps"));

 // If the user hovers the mouse over the button, the global tooltip gets set
  GUI.Label (Rect (0, 50, 200, 100), GUI.tooltip);

}

It reacts perfectly in Unity itself just reacting to Mouse Over, but when exported to the Web Player the Labels Appear when pressing any key also?!

Why is this happening in WebPlayer?? How do you stop it
