Lock the progress bar in the Adobe Captivate 5.5 playbar.

I recently read some interesting postings from cpguru website. One of them is how to lock the progress bar.

(http://www.cpguru.com/tutorial-lock-the-progress-bar-in-the-adobe-captivate-playbar/)

It says that we can lock the progess bar with simple three lines of AS2 code.

this.stop();

delete _root.cpPbcBar_mc.pbcBar_mc.pbcSlider_mc.onMouseDown;

delete _root._level0.cpPbcBar_mc.pbcBar_mc.pbcSlider_mc.onMouseDown;

I would like to use this code, but my captivate version is 5.5, which means

I do need to have AS3 code. Is there anyone who already figure out how to do it with AS3?

If so, could you give me some guidance.
