Still getting niggly with this. There has to be a setting somewhere?
My Folder:
Second identical folder on another user:
Options 1: (same in both users)
Option 2:
File associations are the same for both users and Windows Photo Viewer is the default for as much as it can be.
I have removed and refreshed the icons cache.
What next? (apart from setting up another user as the error user is the main Admin account and was used to install all the software, hence that user name is plastered all over the registry)
