First: thank you msl and waterwingz: you have both been very helpful and patient.
Script runs on my S95(k) perfectly if I load CHDK 1.2.
I also note that dark frame runs ok in 1.2.
But no remote function in 1.2 (unless im missing it).
Also lots of developer 'stuff'.
Much looking forward to a user-released 1.2.
Once again, many thanks to both of you.
Cheers
Garry
