Oh Mr. Helliferocious is so right on the button thing but it gets even worse. Have a look what the Preview.app application in Mac OS X 10.4 has in store for us:
One word: dis-gus-ting.
Background: on the Mac, the default button is on the right. The cancel button has to go to the left of it. This is probably the first Apple branded program doing this kind of thing since the invention of Macintosh. And now, the “greatest” release of Mac OS X brings us this silly Windows-convention that never made sense (and as you can see even the GNOME people convverted to this model while KDE made it at least configurable).
Maybe Apple is hiring its programmers from Microsoft right now. Or the QA department. I don’t know. However, this has to go away.
