Orion WM -- Error: wrong number of arguments

[Puneet <schemer@gmail.com>]

Greetings All

I am trying to run orion-wm.

When I try to split the window using key bindings "M-s h", it prompts
me to specify what kind of window manager is desired by me. But then if
I press S, M or Esc key, the wm gives me the following error. What
could be wrong?

Error: wrong number of arguments
       ('#{Procedure 19481 (unnamed in unnamed in spawn* in ---)}
'(x-warning "BadWindow (invalid Window parameter)" "X_QueryTree"
2097190 #{X-error}) '#{Exception-continuation (pc 22) (signal in
scheme-level-0)} '#{Procedure 1319 (unnamed in
continuation->procedure in wind)} '#{Procedure 1319 (unnamed in
continuation->procedure in wind)})

Thanks
Puneet
