Hi,
@turbojohan I’ve been having the exact same problem. Originally I was getting a 404 message from the CSS trying to load one of the FontAwesome files. So I removed the declarations for that from the CSS and still having problems.
@sewpafly there’s no obvious reason as to why this is happening. I’m using whatever the latest version of Chrome is at the time of writing this reply. But I’ve also tested in IE 11.
What appears to be a workaround (or at least works for me because refreshing only worked a couple of times, bespite 20+ refreshes of the page) is to simply click to another admin page then use the browser back button. So far, this has loaded the preview image from where you can then crop every time.
@turbojohan give it a go, see if it works for you.
