I am animating a symbol instance using a Timer and a timerListener. I also have
listeners for the ENTER_FRAME event. The animation works until entering the
last frame of the main timeline. At that point the instance variable loses its
reference and becomes null. It remains null upon re-entering frame 1 but
acquires a reference again by the time it enters frame 2. I have a keyframe
with content in frame 1 and an empty keyframe as the last frame on the main
timeline. I am using Flash CS3 and ActionScript 3.0.

I am new to Flash and ActionScript so the answer might be obvious to someone
with more experience.

Thanks for any .

Problem solved.
