Issues with Focus 40 Blue and NVDA

Hey everyone,
I hope someone has run across this and can maybe help me fix it. When in Notepad, reading large blocks of text, my Focus Braille display suddenly jumps back to the beginning of the line or paragraph. This is a huge problem, as it always happens when I'm in the middle of a radio program, where I'm reading some Bible verses, and it of course throws me off. And, it seems to happen multiple times each show.
I use NVDA. Is there a setting in NVDA I need to change, a setting on the focus? Please help!
