How do I lock the toolbar and dock so that they don't disappear from the screen and I have to go to the edge to get them back
Since upgrading (?) to Yosemite the dock and header bar disappear from the screen and I have to go to the edge to get them back. I prefer them to be visible all the time but can not find a preference to lock them. Does anyone know how to do this?
