Hi Shannnon, I cannot obviously speak specificly to your equipment since I am using a voicenote q t, but there are some general things you might keep in mind. I have found in over 16 years of using computer type devices with speech or Braille output that the surest way to get them to lock up is to ask them to go both backwards and forwards at the same time, very quickly. The process of reading a word is, for lack of a better description, a forward process. When you read word by word backwards through a line, at least on a computer, you are going backwards in the display and forwards in the reading. Because the computer performs the tasks it's asked to do sequentially to a degree even when it can multiprocess, and certainly when it cannot, what you get is move word back, read the word forward, move word back, read the word forward and so on. If you manage to ask the system to move back twice before reading forward the first time is finished processing if not performing, I've found things can get pr etty jammed up and lock up totally. I have no reason to believe this would not be true on the braillenote line as it is on computers and other notetakers. If you want to test it out, try editing a document on your computer in some word processor and use the backspace rather than the delete process to fix mistakes on the fly as you type. If you're fast enough, you'll lock it up.
So it may be supersticious behavior in this case, but try slowing down the demands of direction changing and see if that doesn't help. .
