I'm experiencing an issue across multiple platforms where scrolling down with the mouse wheel works fine, but not scrolling up, while using vim within a tmux session within PuTTY. Any ideas? Maybe something in putty to sort out (Specifically, I'm using PuTTYTray, but this seems to happen in vanilla putty too)
My ~/.vimrc mouse setting:
set mouse=a
And my ~/.tmux.conf
set -g default-terminal "screen-256color"
set -g history-limit 300000
set -g prefix C-a
bind-key C-a last-window
bind-key C-a last-window
bind -n M-Left select-pane -L
bind -n M-Right select-pane -R
bind -n M-Up select-pane -U
bind -n M-Down select-pane -D
bind D source-file ~/.tmux/logs
set -g base-index 1
set -s escape-time 0
setw -g aggressive-resize on
#set -g terminal-overrides "xterm*:XT:smcup@:rmcup@:kUP5=\eOA:kDN5=\eOB:kLFT5=\eOD:kRIT5=\eOC"
setw -g mode-mouse on
