I do a lot of wordpress. All my websites are running wordpress, including this one. When I do a post, I like to attach a photo as well. Well, after I click on “Add Media”, I usually open a Windows Explorer window and drag and drop onto the Add Media window in the browser. This no longer works. I get the Red Circle with a Line Through It as the cursor meaning that I can’t drag and drop it into the browser window.
Note that this is something I’ve done hundreds of times with WIndows 7, and it has always worked fine.
