Hi...I'm working on a PC as well and have to thank you for taking the time to find a work-a-round...
I'm sure once I learn more about Wavepad, I'll be able to use it to isolate these sound bites.
In the meantime, your suggestion worked like a charm and got the job done
(and I didn't waste another couple of hours trying to make this work.)
So again, thank you and your help is greatly appreciated.
