This could be linked to the "keyboard navigation" function, which moves the cursor on the page when you scroll with the arrow. Or maybe in this case jumps around things on the page.

You can enable the use:

  • F7 key
  • "3-bar" menu button (or tools) > Options > advanced > general mini-onglet > uncheck the box 'always use the buttons cursor to navigate through the pages.

A little luck?
