Capi input model on Mac OS X 10.7 for key/character does not work!

I am trying to run the input-model.lisp example under:

examples/capi/output-panes/input-model.lisp

However, except mouse inputs; key and char inputs do not work.

I am on Mac OS X 10.7 running Lispworks 6.0 Personal edition.

Any ideas appreciated?

Thanks,

Deepak
