Hey all,

this is driving me nuts.  
I have a movie, in it lies a button with which I jump to another position in the \_root timeline.  
At that position is a stop(); command.

The movie just wont stop while this is running in another mc1 deeper in the file  
:

```auto
stop();
onEnterFrame = function() {
	
c=Math.floor(Math.random() * (1500 - 0)) + 150;

var Interval1 = setInterval(function () {
b=Math.floor(Math.random() * (7 - 0)) + 1;
gotoAndPlay(b);
clearInterval(Interval1);
}, c);
}

```

What this does in the mc1 is basically creating a random number between 150 and 1500 and a random number between 0 and 7, then jumping to a random frame (numbered from 1-7) after waiting for a random time (150-1500ms).

My \_root stops properly when I remove the code posted above.  
Why is this happening and how can I have a mc1 in my movie which waits for a random time and then jumps to a random frame, while I want to move around in my \_root timeline?  
I should add, the mcs1 which wait and move to a random frame are non existent on the position I want to move to in \_root.

Could that be part of the problem?  
Do I have to somehow remove the wait and choose random frame to jump to function in mc1, when moving around in \_root? :crying:

How would i do this?

Any help is greatly appreciated,  
dual

If your frame rate is more than 6 fps (which I’m sure it is) then the onEnterFrame function is always triggered in less the 150ms, meaning the interval is reset before the interval is ever completed.
