I've switched from using screen a while back to using tmux. I have a tmux config which uses screen's Ctrl+a sequence, instead of tmux's default Ctrl+b.

However, one issue I've found is that if I press ctrl-a and then hit p for the previous screen, or n for the next screen, without releasing the ctrl key, tmux ignores the key sequence. If I press Ctrl+a, release the Ctrl, and then press n or p, it works fine.

Any thoughts on what might be wrong? My config is as follows:
