I have a movieclip with an image fading in and out (using an actionscript tween class set to yoyo). This movieclip is loaded into a dummy movieclip when a button is pressed. The first time you click the button the fading movieclip plays as it should, fading in and out continuously. However, the second or subsequent times the button is clicked the fading movieclip goes crazy, half fading in/out and half jumping from one alpha value to another. Does anyone have any idea why this might be happening?
