I finally found time to work on this again but it first I had to recode it into an HTA so I can have a proper GUI and installation set and things like a preview window of most recent downloaded image.

It's still free, still Windows only, but starting to get a bit more interesting. I'm already working on the aperture and shutter control -- mostly so I can get that involved in time laps.

Thanks.
