Hi there,
When using Imagecrop, I've tested it out in two ways:
Firstly I opened a previously made content with an image field, removed the image, re-uploaded and cropped it using the new crop tool. Then I scroll down and click save, and the page refreshes but takes me back to the same editing page but nothings changed. If I create a new content, fill in all details and upload/crop a new image, then click save, the page refreshes but it has emptied the things I filled in and not created/saved the new content I just made.

So basically, the Imagecrop has disabled my Save function!

Not fun.
