Working with the new version 1.1.4977. Starting a new script, added a section I called loop.  I clicked in the new text box and inserted text in it and did some editing there, and then I dragged the text box to the new loop section in the script . This was the only thing that was in the script. I went to do some more editing by clicking on the edit button and I got a white window and the spinning ball. Had to force quit.
