Hi Nicholas...
Try running "ls -la", then opening any file with 'vi'.
When 'vi' starts, the result of 'ls -la' get overwritten in tmux.
With screen or the plain terminal, the result of 'ls -la' get moved up but
not overwritten, so I never lose what was printed on the terminal.
This is my .tmux.conf:
----
set -g history-limit 200000
set -g set-titles on
set -g set-titles-string '[#I:#W:#T]'
set -g status-justify right
set -g status-keys vi
set -g status-left '#[fg=red][#I:#W]'
set -g status-left-length 50
set -g status-left-attr "none"
set -g status-right ''
set -g status-right-length 1
set -g status-bg 'yellow'
set -g default-terminal "screen-256color"
set -g terminal-overrides '*:smcup@:rmcup@'
setw -g window-status-current-format '#[fg=red,underscore,blink][#I:#W#F]'
setw -g window-status-attr dim
setw -g window-status-format '#I:#W#F'
setw -g mode-keys vi
setw -g mode-mouse off
setw -g alternate-screen off
----
And this is my .screenrc:
----
termcapinfo xterm ti@:te@
defscrollback 100000

Virtualization & Cloud Management Using Capacity Planning
Cloud computing makes use of virtualization - but cloud computing
also focuses on allowing computing to be delivered as a service.
