Sorry I can not type in Chinese at this moment. With photoshop, I made a button along with a text in gif format. When this button and text was imported in Macromedia Authorware 6.5, the area around the text was transparent, but the enclosed area of the letters like A B D O, was solid white, not transparent. I did not get any solution and i had to change the interface design of my project. I really appreciate your reply and i love the pictures you posted very much. Thanks again!
