Tweens don't work on AS2 swf's loaded by AS2 swf's the second time

Tweens don’t work on Actionscript 2 swf’s loaded by Actionscript 3 swf’s the second time.

Please check the attached file. Open the master.swf. Click on the button to load a AS2 swf. A black box will be animated by a tween. Click the same button again. The box won’t be animated.

The same thing happens if you open a AS3 swf before or between.

Any ideas on what’s going on and how to solve it?

Does anyone can confirm this behavior?

Thanks
