Hi David,

Thanks for your response! 
Making the change you suggested in the slide properties solves the echo 
problem: the echo now goes away when the slide finishes.

However, I still have the countdown problem... because I'm now defining a 
specific duration for the slide, the countdown clock script does not work; 
for it to work I have to define its  Duration to 0 (zero).... there might 
be another way (other than the countdown script I'm using) to display a 
timer in the slide while it is on.

I really appreciate your help!
