I am back to high-speed cygwin. In the end I had to set my HOME to something. Otherwise cygwin would set it to my Windows HOMEDRIVE, which goes out to the network. I have a laptop and want it all to work when disconnected. I set up a C:/cygwin/home/$USER and put that in my Windows environment as HOME. It has been a long time since my primary HOME was a *NIX box so that didn't occur to me before. I don't remember having any speed problems until recently. That is why I thought it was either the change to WinXP or a newer version of cygwin. I will check into the ncurses issue and maybe even go poking around in the source code. Thanks again.
