[duxhelp] Jumpping display

Aloha,
While formatting a .dxb document, my display suddenly jumps back about 30 to 35 lines. Example: while reading page 2 line 10, I suddenly found myself on page 1 line 4. This is the third file in which I have experienced this issue. These have been basic text files in paragraph format. I have been having this difficulty since SR2 but not before in 10.6.
