No, I don't think that could be the problem. I am just using ssh between local machines and there is no firewall between them. It also often seems to happen to a shell as I switch away from it to another one. One suspicion is that something is sending a signal to the shell as it switches, and bash sometimes doesn't handle that signal properly. I also should have mentioned that I have been running bash as my default shell for years under Linux and have never seen this problem there. Thanks for the suggestion. -- Carl Johnson [email protected] _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[email protected]"
