Why do all of the original swf's play, but only 1 plays when copied?

Hi all,

      I joined this forum after searching it, and Google, for this answer. I am running Windows XP SP3. The Adobe Flash Player home page ran a test and says that I'm running version 11.1.102.55, although whenever I open a swf file in Adobe, the Flash Player window that opens says that it's Flash Player 10. The problem is that I have 6 swf files on my slave drive. All 6 play fine from that original location. I've noticed that when I copy them and try to play them on either another computer, the same computer's master drive, or even the same computer's slave drive in a different folder, 5 of the 6 won't play. The 1 that does play is always the same one. I also noticed a difference in the 1 that plays everywhere. It doesn't start automatically like the rest of them do. It has an arrow to click to play it. When the 5 swf files that will only play from the original folder are played, they start to play automatically when clicking on them. The Flash Player window opens without showing an arrow to click on. I hope that this information is helpful, and that someone knows what is happening. Thanks.
