cwm window in all/no groups

I'm using windows groups with sticky.

unbind-key all

bind-key M-1 group-only-1
bind-key M-2 group-only-2
...
sticky yes

Usually I can keep all my windows in whatever group they were opened in. On
occasion, I must be typing in some strange key combination and I end up
getting some or all of the windows on my current screen bound to no group.

I don't have any keys bound to 'window-stick' which seems like it would
do exactly this. I don't have any keys bound to group-only-0. When windows
start going into all/nogroup mode, it becomes very frustrating. I can't focus
into a nogroup xterm for typing unless I kill or move any windows which are
members of the current group. I can't move the nogroup windows either. I
can't close them using the meta key delete. These nogroup windows have
some very annoying properties, appropriate for xconsole perhaps.

Does this sound familiar to anyone?
