Don't know if this is normal or not as I never noticed until now. I know that the green butotn is not like windows, it doesn't maximize. Instead it enlarges the window to fit the content correct? The only apps I find that do this are Finder ,Safari textedit (if I have wrap to page on), addressbook I tunes goes into a mini player.. unless I press option(where it just moves the window into the middle, but staying the same size) Firefox switches from fully maximized screen to my last sized window, Mail acts the same way as firefox... So I am wondering if this is normal.. For the zoom button to be inconsistent between apps (I suppose iTunes is an okay exception when it switches to the mini player).. Is it just me that feels this makes no sense? I find it really hard to get used to when the button does one thing in certain apps then something completely different in another.
