Dragging an image into an email

Wondering if this is only happening to me, or if there has been some update to alter this feature: I am no longer able to drag in image (using the image icon in the upper right-hand corner, next to Token) into an editable section of my email. That area is now grayed out. In the past, I had always opened up the editor and dragged it straight in. This feature is not working for me from the editor, nor by simply dragging it into the email itself. I now am forced to go find my image, grab the url and insert that way. Takes much more time--especially when i'm not always sure of the names of my files.
