Thanks for your help Rusty.

This is becoming a habit with posts coming in as I am writing one. Hi Andrew, thanks for your input too. What you say is what I am experiencing. If it wasn't for the fact the the GStar camera I use has only Windows software to drive it, I'd be running off an Apple. I think 2 laptops running gets a bit messy. But then again.........maybe.

Hmmm. Would save a lot of bother.
