The video attached is a screen cast highlighting the difference in JAWS behavior activating the next item button with the Virtual Cursor on and off. JAWS does not announce the changes to the Live Region (e.g. "Item 2 of 3") when activating the button with the Virtual Cursor on. It does when the Virtual Cursor is turned off by pressing Insert+Z
