Is it possible to wrap text (messages) in the Message Window?

As you can see in the screenshot, which I provided in my previous message, some lines are too long and displayed just partially. So you need to scroll them right (using a scroll bar in the bottom of the page) in order to see them all. So, is there a way to display all the lines wrapped to the window width (without each time scrolling the window right if the lines are too long)?
