Nividia GF FX5600 XT, used everything from WHQL to untested, unoffical, leaked & hacked beta drivers with the same issue. Latest updated patched version of windows xp, direct x and sonic stage. Think its something to do with custom visual styles trying to alter the look of sonic stage, which then trys to restore it to the sony default. Which goes round and round till it crashes (hence the flickering black). So my moneys on sony taking short cuts with the sonic stage GUI, which means its not fully compatible with anything other than defualt windows visual styles. So by turning of visual styles in the compatiblity settings and praying that a large rock falls from space upon the SonicStage dev team it should be sorted. David
