Text in User Guide is truncated because of large graphics

I have to use a scroll bar to see the end of the text in this page: https://confluence.atlassian.com/display/DOC/Confluence+5.0+Release+Notes.

Just to make it worse, you have to scroll down to the scroll bar and move it, then scroll back up again so you can read what's not being shown.

It doesn't matter if the browser is at full screen or if the sidebar has been hidden, the text still runs off the screen.
