I have a problem at one computer only (this problem is not appearing at other computer), the problem is:
When scrolling down and up using the keyboard arrow through the link (to select one of the items as an example), it is not appearing the cursor position (it is not showing which item I am selecting). What could be the reason?
In other words: while scrolling using the keyboard arrow within the link to select the item, the blue shade that should show the cursor position (which item is currently we are standing), is not appearing. What could be the reason?
