I have found that the red loading notification sticks and never ends when I am adding text to my site. It doesn't seem to bother me when I am only adding pictures. I have tried the escape button to no avail. I have simply closed the site and started again but it never works quite right. The best thing to do when that loading thing pops up is to close the whole thing down and go back to internet to bring it up again. What's frustrating is that this repeats over and over. It takes forever to make changes to the site!
