I've noticed (on more than a few Linux servers) while I'm editing a configuration file via SSH the text cursor loses it's place. The only way to regain its correct visual placement is by stretching the terminal window. It's as if it's lagging up; but I'm on a solid connection.
OS: (CentOS, Ubuntu) SSH: Standard SSH server on both ssh distribs (via MAC client terminal) Editor: Nano
* It happens on any text file size.
