CS4 Application Background Color

In CS3 and earlier, the application background color came from the Windows application background global property. In CS4 the central area seems to be (127,127,127) and I can't figure out how to change it. I have "open documents as tabs" OFF because I like individual windows, so the bright gray background is distracting.

How do I make it darker? There doesn't seem to be a property in Preferences->Interface.

Thank you,

in older versions you shift click on the background (i think it's called the matte) with the paint bucket tool and it applies your current foreground color...
