Animated GIF

[edward cawley]

II have an application which uses several animated Gif's that was  
running with no problems. I had a button which went to a test card. I  
modified the stack to drop the test button. The gif on that card had  
an icon for the button. I used pixen to erase the icon image from Gif.  
The edited Animated Gif run fine in Quicktime as does the original  
Animated Gif. If I replace the original gif with the edited gif, using  
the same file name the Gif image shows up but does not animate. If I  
replace it with the original one it works fine. Any ideas whats wrong?
