Problems playing animated gif on label again

Question

I have program that is displaying a graphic representation of a wave file this is a cut down of it. I am using a mouse listener to detect the mouse wheel and from that I am zooming in on the wave graphic or zooming out.
The problem is when I zoom in a Jlabel is displayed with an animated gif saying �zooming in� that work fine. But as soon as I zoom in again, the Jlabel will not display the image again or the zooming out image.
I an new to java so be kind to my code
Any help would be greatly appreciated
