Weird bug today, only on Mac Firefox. The last tween didn't draw correctly and left artifacts trailing along its path, so that the logo, rather than gliding into position, stayed partly out of the frame. Any little nudge to Firefox (zoom change, menu click, resize…) would startle the Flash player into finally drawing the end frame correctly. This in a very expensive 1-day Youtube masthead placement! I tried moving the tweening symbol out from under its mask; no change. I tried changing the tweens to be scripted instead of timeline: no, that last tween still didn't render fully.

The workaround was to put a constantly looping stage-size graphic in the background of the parent swf. This reminds the Flash player to keep updating the screen.
