When I crop an image selected directly from the Media Library I can Crop then click the X to exit the window. But when cropping an image that's part of a Gallery in a post/page clicking the X does not exit the Crop window, I have to refresh the browser to get back to the Dashboard.
You will also notice I have to click twice the "Crop Image" text button to open the Crop window.

Other than that I really love the plugin, it is very very helpful!! Thank you!
