Have a AMD Radeon HD6450 powering our main projector and the monitor in the soundbooth. Have an HP Docking station connected via USB that feeds the foldback monitor. This configuration has been working fine with EW2009 but it's acting really goofy with 6. I get nothing at all on the foldback, but if I drag an explorer window or something over onto that monitor you can see the text appear briefly. Any idears??
