What do you hate about OS X or pet peeves?

1) I hate that the menu bar is fixed at the top of the screen. Your top window in view may not be the one currently selected. Windows just does this better. There is never any confusion what menu bar belongs to what window. This is my number one pet peeve.

2) Maximize button does not do full screen. I hate when press that green button and it only stretches the windows vertically. I hate this!!

3) There is just so many nuances where Windows is just better. It would take too long to explain. Let me just say windows management is better in Windows.

What are your pet peeves?
