I forwarded this situation to the lead developer.Thank you for your feedback.

Clint share the app again to this address interactbuilder@gmail.com and also let us know the name of the app.

Clint what's the name of the app?

Hi Cathy here is a tutorial of a drawing page with erase option to:
http://www.youtube.com/watch?v=9Zu0I-NST_Q

And here you'll find the sample app for this:
121 - Draw Page.zip

Try to chain the Jump behavior to the PlayAudio behavior and also put a delay on the Jump behavior equal to the audio file.

Here's a sample app for this situation:
280 - Jump with Audio.zip

Try to chain the Jump behavior to the PlayAudio behavior and also put a delay on the Jump behavior equal to the audio file.

The refresh on those page is working great.

The random settings could repeat twice, but the arrow will animate with different duration.

At this moment there isn't an option for this. I will try to find an alternative way to do this and will let you know.
Here is a sample app of a way to do this:
116 - Animation Random Time.zip

So basically I have a frame element (bike) that will do a static animation at a random time. The random time is dictated by an off screen intersection. The elements that are intersecting are:
an arrow that is doing a linear animation with replay with random duration
and a transparent element that is place on the arrow path.
When those two intersect, the bike will animate. We will not know when the bike will animate because of the random duration of the arrow animation.
