i've finally got kppp to connect to my isp but after the connection is made
i try to ping  and the terminal window hangs. i open up netscape and it
can't find anyplace. i try to change the mail account from within netscape
but that window hangs netscape. i endup having to disconnect. anyone have
any clues of where i should start?

thanks
