The past few days, uploading an image hangs after clicking the Submit button. I end up closing the pop up window. Going back, the image loaded, but then, when I upload another image, I'm unable to stretch the window to select the image (mouse remains an arrow and doesn't change to cross hairs). I then need to close the page and go back in. I've tried multiple browsers with the same results. I also tried clearing the cache with no improvement.
