Drag and Spring Back, Refresh Idle

[ush]

Hi,

I'v got two more simple questions.

1. If I had created slider which springs back to it's default position when it's not draged how can I control the "speed" of the spring?

2. Is there any other simple way of refreshing MC when it's idle than using this code:

onClipEvent(enterFrame){
count += 1;
if (count > 500){
gotoAndStop (4)
}
}

onClipEvent(mouseMove){
count = 0 ;
}

Thanks in advance for any help!
