Sorry! In glass not refraction on.
It is necessary:
    photons {reflection on refraction on target } - Works :) :) :)
Thanks!

Glad to have helped. ;-)

I would increase your max_trace_level a bit, though.

you may wish to add "pass_through" to the glass in window,
then photons should ignore it prior to hitting the target.

On this site good support.
