I am currently reading the following tutorial: [http://www.kirupa.com/developer/actionscript/random\_motion.htm](http://www.kirupa.com/developer/actionscript/random_motion.htm)

And I come across few questions.

1. How can I adjust the boundaries for the moving dots? To be exact, the area I am working with is 600 x 900. And on the height, the top 120 px, I have buttons and such, so I don’t want the dot to move into that area. So far, I tried…  
width = random(900);  
height = random(480)+120;  
However that doesn’t solve the problem…

2. How can I pause the movement of a dot when the mouse is rollover?

Thank you for your help and attention.
