Phil: For what it's worth (2 maybe 3 cents?):
Here I'm using Win XP/Pro - DXBase2003 on an Athlon XP+ machine with high speed cable modem. Upon closing the Internet connection to N3RA DX cluster it IMMEDIATELY and completely disconnects. No muss, no fuss. I just wanted to add another observation to the collection. Prior to recent DXB upgrade, DXBase2002 also disconnected immediately under XP/Pro and Win98SE with a dial-up ISP. Good luck, it seems you have a bit of a mystery on your hands! 333-3333 George K3GP
