We found a workaround to make the crop tool work. When you open CE, just click on an image file in the File Navigator in CE, and THEN click the Shapes menu. To rephrase: don't touch the Shapes menu until after you click on an image in the Navigator, such as "YourFacade.jpg". The crop tool should be enabled and should stay enabled until CE is shutdown. The way to not have it work is to open the Shapes menu before clicking on an image. As previously stated, this is a bug, but hopefully this will work for now. I say hopefully, because we need you to test this workaround. If you find exceptions to this, or if this just doesn't work for you, please reply. I didn't test on versions before 2015.0.
