Prevent image from 'obscuring' onmouseover event below?
<p>For a 'shooting gallery'-like game, there are images with an onMouseOver event that will show a crosshair (which follows the mouse) and an onMouseOut event that will hide it.</p>

<p>However, the instant the crosshair becomes visible, it covers the below image, activating its onMouseOut event which hides the crosshair.</p>

<p>This creates a 'flicker' effect which is very, very ugly.</p>

<p>Is there a way to prevent the crosshair image from obscuring the target below?</p>
