Could you check that link to your review please? Even with the %20 stripped out it still doesn't work. Many thanks. I didn't realise the green key was a zoom in/out! I think there is a need for a basic guide on how to use Viewranger in the real world, Like most manuals, the VR simply says what each function does, not on how to stitch it all together. Having come from Satmap (hopeless) I was aware of the need to start and stop tracking, converting it etc, but had I been a total newcomer, I would have found this hard to realise.
