Byobu looks very broken in PuTTY. I've already fixed the key mapping issue, but this issue isn't specified in the man page or even Google:
Notice the misplaced position of the list of windows, the broken selector position, the duplication of the last window, the random a in the top right, and the misplaced apply option. You can't see this, but the last option is not selectable.
Is there some option in PuTTY I need to use in order to see this correctly?
