Songbird interface doesn't recover fully after being minimised

When the songbird window is minimized then reopened, the panels remain grayed out as though it were in the background. While some controls respond to being clicked, the effect is not seen in the window (e.g. clicking the grayed pause button will pause the music, but the button icon doesn't change as it would normally)

Using Version: Songbird 1.2.0, Build 1146 (20090616030100) on Mac OS X 10.4.11
