Hi: I was streaming a video via the web with Firefox and using Adobe Flash Player. But it appears I've encountered a problem where upon closing the video, Adobe Flash Player doesn't want to close. I get this weird message: "A script in this movie is causing Adobe Flash Player 10 to run slowly. If it continues to run, your computer (iMac) may become unresponsive. Do you want to abort the script? Yes No." I abort the script but pretty soon my iMac begins to suffer his issue again. When this message appears my iMac literally slows down to a snail's pace. I can't seem to abort this problem even when I answer in the affirmative to abort. What to do?
