Hi,

If animated GIF is <1M, animation is correct in Java and in Netscape browser.

If animated GIF is >1M, animation will stop in Java. It will run correctly in
the Netscape browser.

I have tried the code, with overriding update and using media tracker, neither
will work with animated GIFS >1M. I am including the media tracker code. You
will need to create an animated GIF >1M. I used ImageMagick.
