Okay, perhaps this has been answered before, but I can't find that answer.
I've been having problems with the masking effect in Flash Professional. You see, I had created some text, and then rigged a glint to go across it. When played in the main timeline, it works perfectly. However, when I go to test the movie, the mask doesn't work, and instead I see the entire glint rectangle moving across the text. This is very irritating. If anyone knows how to fix it, that would be great.
Also, I'm providing a download to show you what just what's going on: http://www.mediafire.com/download/qveb3d9hw4whuw6/Flash_intro.fla
