Originally a long time pc user etc etc, totally happy with all my Mac's (4 of em ) and did notice when I first using them - closing windows down. Obviously M$ red x closes the application down, ok. What I dont understand is that when I click the red x on OSX windows various things happen depending on what program/window you have open. eg, point one: Mail, I double click the top bar, the mail app minimises itself genie style to the bottoms of the screen. But when I click the red X on Mail, it dissapears but as you can see in the dock by the small black indicator the program is still running. point two, this isnt the same with "system prefs" you click the red X and it unloads the system prefs (ok this might not be an app and only a window) point three, Firefox, you click the red X and it also wants to close the program down. Ok so its not an Apple app, but you can see where I am coming from, all of the windows don't appear to have the same actions when you click the red X and its only because Ive been using OSX for 8 months that I am used to it now and know the different results. Any reason for this?
