Bug in Read Aloud - skipping words on page down

I was listening to some homiletical commentaries today (Pulpit and Preachers), and noticed that whenever it moved the page down to follow along with the reading, several words were skipped by the read aloud voice.

I noticed that in Preachers, the shift happens at the end of each screen of text, regardless of whether page numbering is on, but in Pulpit following along with the text only occurs if page numbering is on. In both cases, words are skipped when Logos pages down to follow the text to speech reader.

I rarely use this feature, so I don't know if this is new to version 5 or has been around for a while.

Using Win7 & OS provided text to speech module with default voice (Microsoft Anna).
