When I click on an item on the main menu, a drop down menu appears. Normally when hovering over an item on the drop down menu, the item directly under the mouse pointer is highlighted. This is expected. Sometimes the highlighted item is instead, the item just below the item that is directly below the mouse pointer. This is not expected. The problem in intermittent and I have not yet identified all of the conditions that are required to reproduce it.
