And I am so embarrassed by asking this! I just did a fresh install of Mavericks because 10.9.1 came out and I wanted to see how a fresh install and an instant install of 10.9.1 would effect some performance and other things (if at all!) Anyway, for some reason when I close applications using the "Red X" in default Apple Apps (as that is all I have so far, have not installed anything else yet) it is literally closing them, not simply putting them how the default setting usually works, which is to basically minimize it in a way and not close it completely. Now, I have not touched ANY setting so far and as far as I remember this is not default Mavericks behavior!! For example, if I have Safari open and browsing and I hit the X it is acting like I am Cmd+Q Safari, or any other app for the matter. Is the default in Mavericks and I am not remember or is something off here and if so what is the option in settings to change this? Sorry for such, what I feel is a dumb question but I have searched the web and what not and cannot find anything about this. Thank for you help in advance and did I mention I am so embarrassed!!!!!
