I have had nothing but profound problems with FC4 and FC5. Is your soundcard set to full duplex? So you can send and receive if you're using sound out / microphone in at once? The default is half duplex and an upgrade would set it like that. I think... that sounds like your problem. Note: full duplex will eat up some cpu. I use KDE so going into control center and editing the sound setup is where I would change the duplex option. Hope that helps. ONE DAY, when I retire to a sailboat, I'll want to understand how boaters use radio to send / recieve email html, etc. Is there a good website you'd recommend? Ric
