Thanks John,
I always fear that I'm gonna make things worse when I try to do things like this...oh well. But, I have tried.
The settings were different, the speakers were 24 bit, 44100Hz and the microphone was 1 channel, 16 bit, 44100.
I changed them to match, 16 bit, 44100 and I'm hoping the thing doesn't explode on me.
To be honest, the fact that the initial recording seems to work find and only subsequent re-recording causes the problem confuses me but here I go to try and test it. I'll let you know my results soon. If I'm way off base, laugh and let me know so I can try to get back on track.....Into the valley...
