I'm finding that my code wraps ... but not until it has run off the right edge of the editor. I end up having to scroll to the right in order to catch a few characters that are hidden over there, then scroll back to be able to see where the lines begin on the left.
You can see, in this screenshot, where the code runs into and beyond the scrollbar.
How can I fix this? I'm sure it's a preference I'm missing somewhere.
