I use an early 2011 15" MacBook Pro running Mavericks. Occasionally, when I open a new page, the cursor disappears. When I move my finger on the trackpad, I can see icons activated when the invisible cursor passes over them, but this isn't very useful. I can't pin it down to any particular application; it seems random. Usually, when I close the page and open another, the cursor reappears. Has anyone a solution?
I should add that problem usually occurs when using Photoshop.
