Comment 3 for bug 990623

I have witnessed what you describe, hjd. IMHO, it is not a true hover feature but the result of some transparency in the borders. The new image temporarily overlays the original image until the mouse pointer is moved. By moved, I mean any movement of even just a pixel from its position when the click was performed results in the erasure of the underlying (original) graphic. So, I attribute this anomaly to transparency in the borders that reveals the mechanics of the image change.
