Today, I found that clicking on the "image upload" icon now presents one with what appears to be a dashed "drag-and-drop" box containing the message "Click Here to upload image". (Just a day or two ago, I was getting the file selection window I'd been getting for close to two years.) However, I am unable to get this to accept an image by dragging either a .png or a .jpg into it.
Has there been an alteration to this function recently? Is there something in particular I should know about using this feature now? Thanks.
