Stange cross hatching/banding

I have a question regarding adding new textures. I use Photoshop 7.0 and DXTbmp to convert the BMPs to work with the aircraft model. I have noticed this more with the Flight 1 Text-o-matic (perhaps I should ask this at the flight1 forum, but I will take a chancer here that someone knows).
Anyway, after creating a texture and flattening it, once I get the BMP loaded onto the plane, I will notice some yellowish cross hatching/banding on white textures in the game. This is very noticable when zoomed in on the plane. When I zoom in on the textures in Photoshop, I don't see the banding. Any ideas on what may cause this? I usually save my BMPs in RGB at 32bit.
Thanks all.
