Probably resolved ...

I ve found than using only my apple cinema display 24" alone ( this one use ADC to DVI adaptor ) and the Black Flash occur .

I ve plug another Monitor in Hdmi and all was Good .
I ve then Add my cinema Display as secocnd Monitor , And all was Good too .

So Maybe just a little bug caused by ADC to DVI adapteur when Monitor alone .
