Occasionally when receiving a message that has been forwarded, there will be one or more vertical black lines at the left side of the reading pane. This sometimes pushes the message text off the right side of the pane. There is no horizontal scroll arrow to allow seeing the entire message. The entire reading pane can be shrunk using the magnification slider, and this will then show all the message. Is there a way to edit out these lines so the message would appear as originally sent? If I send a forwarded message on, I like to clean it up as much as possible. I have not found a way to delete the lines without deleting the entire body of the message.
