Adding fsdfx in Panel.cfg. How is this done?

Hi,Does anyone use this and if so, how are you adding it? My Level-D panel config is already using all pop-up windows as shown below. I know it can be done as one video on you-tube shows it being used but I sure can't figure it out:( I'm a registered member at Level_D, but I thought I would ask this here as it's not really a Level-D problem per say.From my Level-D panel config using FS2004:[Window Titles]window00=Boeing 767 Upper Panelwindow01=Boeing 767 Main Panelwindow02=Boeing 767 Upper Panel First Officerwindow03=Boeing 767 Main Panel First Officerwindow04=Boeing 767 Overheadwindow05=Boeing 767 Pedestalwindow06=Boeing 767 FMCwindow07=Boeing 767 MCPwindow08=Boeing 767 Standby Instrumentswindow09=Mini Panelwindow10=Main panelThanks,Jerry
