Flash MX ActionScript: Beginner needs help with "movement follow mouse"!

Hi, I am new to the forum. I was asked to create something similar to what’s on [COLOR=#800080]http://www.schech.net/de/start.html[/COLOR]. (Skip the intro and click on #1 Slide). This nice flash has a highlighted bar that moves horizontally with the mouse movement, while the background image move vertically too. Does anyone have any idea how they did this? I have limited knowledge on ActionScipt. I have searched everywhere and only found several tutorials like moving a circle mask with mouse movement. I am desperate.

If anyone can share his expertise, I’d appreciate it!


BTW, any recommendation on a good, easy book on ActionScript for beginners?
