When I worked on the cantonese lessons under lee.pcwong.org, I experienced the problem with ajax not getting pcwong.org/cgi-bin/cantoneseIn response as well as the SoundManager for the audio.

The problem is fixed with the script is copied from pcwong.org/cgi-bin to lee.pcwong.org/cgi-bin as well as swf file of the SoundManager2 is copied to lee.pcwong.org.
