I forget which thread it was in, I was searching in the network forum and saw it. You can also check the README file in %ORACLE_HOME/sqlplus, I heard that there was something there about it.

I did hear from another guy on this board (Sergey) who stated that his co-worker was able to connect to a v7 database with the 9i client on his laptop. He stated that there is apparently a bug in 9i sqlplus. In your login script you shouldn't have set pause on command. If so it will automatically exit from the application. Sounds like this is your problem as well. Hope this works for you. I am planning on finally installing 9i on one of my servers next week and getting started with it. (That's if I can keep the developers off my back)
