Hello,
I have the elastic movement snippet (from Keith Peters), which works fine until
publishing for Flash 7 player. In Flash 7 leafes just scatering out
with no elastic
interaction. Compiler doesn't throw any errors.
I tried Actionscript 2 static strict type variable declarations, but no success.
Any hint would be helpfull.

And ball button code:
on(press){
startDrag(this);
drag=true;
}
on(release, releaseOutside){
stopDrag();
drag=false;
}

Thank you in advance.
