Can't get panes to re-size with hotkeys

Question

I have a small annoyance whereby sometimes my hotkeys to re-size existing panes doesn't work.  I had changed the hotkeys to move from pane to pane to be Alt-Left (arrow) and Alt-Right (arrow) key.  After looking at the default settings by running tmux's in-pane help (the hotkey shift-?) I commented those two keys out thinking that would reset tmux to its default behaviour.  It hasn't worked so far and I'm not sure where else to look aside from my .tmux.conf file.  It's based on Thayer's own config:
#~/.tmux.conf - tmux terminal multiplexer config
# Based heavily on Thayer Williams' (http://cinderwick.ca)
## Environmental Options
# Enable tmux to use a 256 colour terminal
# Provided the underlying terminal supports 256 colours, it is usually sufficient to add the following to ~/.tmux.conf:
set -g default-terminal "screen-256color"
set -g terminal-overrides 'xterm*:smcup@:rmcup@'
# If you SSH into a host in a tmux window, you'll notice the window title of your terminal emulator remains to be user@localhost
# rather than user@server. To allow the title bar to adapt to whatever host you connect to, set the following in ~/.tmux.conf
set -g set-titles on
set -g set-titles-string "#T"
# open a man page in new window
bind m command-prompt "split-window 'exec man %%'"
## By default, all windows in a session are constrained to the size of the
## smallest client connected to that session, even if both clients are
## looking at different windows. It seems that in this particular case, Screen
## has the better default where a window is only constrained in size if a
## smaller client is actively looking at it. This behaviour can be fixed by
## setting tmux's aggressive-resize option.
setw -g aggressive-resize on
# mouse-select-pane [on | off]
# # If on, tmux captures the mouse and when a window is
# # split into multiple panes the mouse may be used to
# # select the current pane. The mouse click is also
# # passed through to the application as normal.
set -g mouse-select-pane on
## Upon starting to use tmux, I noticed that I had to add a noticeable delay
## between two characters in a command sequence for it to recognize the
## command, for example between the C-a and n in C-a n. This is because tmux is
## waiting for an escape sequence. Fix that by setting escape time to zero.
set -s escape-time 0

No--
In the Motion tab... right click the video in the sequence and send to viewer...
Then under the MOTION tab... twirl down the DISTORT triangle and then check the aspect ratio there... set either to 0, 33 or -33.
Good luck,
