A couple of issues. Firstly the one-click license button is really bad UI and I can see from the forum that this has been mentioned since 2015 with the replies that it will be looked into but not acted on. This issue is an easy fix and so I can only assume that it isnt being fixed as it increases sales. So far I've managed to accidently click on 'license' on 3 images whilst trying to view a larger version and i'm fairly sure i'm not alone in this. All it needs is a check that says 'are you sure you want to license this image?'
