Odd, it should say INFO: <<something>>, not just "INFO".

For example, if it says "INFO: TRACK" then you're in info:track mode and you can't see the visual switching. Try pressing the info button a couple of times and then the visual button a couple of times to see the various screen modes. You have to be in either info:line info:transient or info:off to see visuals.

Does it really just say "Info"?
