[R-7258] in N6.0.4: Scroll bar of the MixConsole

R-7258 MIXCONSOLE: The scroll bar of the MixConsole is now displayed correctly.

This is still an issue on the MAC (10.8.4) N6 64 bit, the scrollbar on the bottom is insanely narrow I have to aim hard to hit it and then it does not always respond… it’s really frustrating
