Sorry if the title is confusing, but when I try to put some text at the top of the question with a comma ending the line and press "save changes", the text dissapears.
You can watch a video of me trying to write "Hi all," as my starting statement and then watching it dissapear when the changes are saved: https://drive.google.com/file/d/0B8nGJZi9RcPHRkZMY2NaZUo0d1k/view?usp=drivesdk
