I am having a strange problem. I have a flash swf file that has AS3. It works fine on all MACs and PCs with client, except I have found one client MAC that displays the swf file as if the AS3 did not run to hide the layers. It loads the swf file, but it looks like it does when I open the .fla file in Flash to work on it. I can't figure it out. I have reinstalled Flash to latest version, I reinstalled both Safari and Firefox. But still in both browsers on this particular MAC the swf file is not working.
