Thanks for the info TIG
Unfortunately its not always possible to find an existing thread where someone is experiencing the same issue as you...
Either way I believe my test matrix has covered when this will cause an issue... and like i mentioned it would appear best to create components in a non-geolocated file... As I am in architecture and the geolocation controls the sun, this is not my default workspace... but I have now learned my lesson!
It would help if the developers would issue such a warning though and at least build in the option into the component settings which I understand from the thread you pointed to, was something that actually existed in v7.
I discovered this whilst trying to make a library of new people and almost blamed your image trimmer! π
Cheers
