@ Whim,
Thanks for you help.
I just downloaded the latest CHDK a495-100f. It is just past midnight Perth, Western Australia time; I will install and play around with the software in the morning.
I have plans to build a three camera motorised panorama array with the A495's. Purely for educational purposes and keep my brain active.
Goodnight from Perth; it is probably early morning in Europe, therfore good morning.
