Hello Eduardo Ochs, > and then use Zsh a bit with comint-process-echoes set to true and a > bit with comint-process-echoes set to nil - use `M-x det' and `M-x > den' to change the value - to see if something changes? First I noticed that comint-process-echoes is not defined in shell mode. Then I switched the shell buffer to comint mode. Then, in both det and den settings, the problem still happens. -------- Zhou Renfei
