This staff is an example. Note that I'm running a 22" monitor so the problem bar my be a bit further off the screen for some - right arrow to bar 14 (or until it jumps for you) and see what happens. I'd be interested to see if you get the same results. This is an excerpt from a transcription I'm working on... Note that the real work uses specific fonts however they are not necessary for things to play up.
