I like the way Google Chrome puts the tabs above the address bar, but I don't like the way the minimise, restore, close buttons are a different shape to every other program's. It means that if I sit the mouse in the top corner and minimise everything, I find that I've restored Chrome, not minimised it.

Is there any way to get these buttons to a normal shape and size?

That's Firefox in front, looking normal, like every other program, and Chrome above and behind, with the buttons at an off-standard position and size.
