Did you download the P-51D from Garry Smith's site? Just curious. I have the plane in FS9 and have never experienced anything like what you describe. I have installed the latest drivers for my video, just booted up Warwick's little gem, and the panel looks like it always has. I don't think anyone has done any modified panels, but I may be wrong.
I'd check Garry's website, if anything is available for Warwick's P-51D, that's the official place to get it.
I use both NVidia and ATi cards in two separate machines.
