You know when you use Safari, Pages, and what not how there are "red", "yellow", and "green" buttons on the top left corner? Well green is suppose to expand the Window, yellow is suppose to minimize it, and red is suppose to hide it. However lately when I click the red button it deletes the window and when I open up the application it shows the start up screen instead of the previous window I was on. It does this with all of the items in my dock now, except iTunes. How do I change the red button to hide the windows again instead of closing them? (Yes I know about CMD + H but I don't want to use that I wanna fix this).
