Dock not auto-popping up
Hi,
As of an hour ago, my Dock (located at the bottom of the screen) does not pop up automatically when I scroll the cursor down to the bottom of the screen. I need to click on it. The happens no matter where I place the Dock. The auto hide and show dock option is definitely selected. I've noticed some complaints online about Mavericks and the Dock, however I've had Mavericks installed for at least 4 months and this is the first issue I've had with the Dock. Could this be a virus?
How do I get this to work the way it's supposed to?
MacBook Pro, OS X Mavericks (10.9.5)
