OK, I have nailed down the exact circumstances and conditions under which the red color disappears.
I can enable any of the options in "rendering options"...I can enable *all* of the options in rendering options (Boy does everything look great with all the bells and whistles on...) with the exception of "enable 3D clouds". If I exit FGFS after a flight with enable 3D clouds checked I lose all red color and the frame rates go to 1-4 fps the next time I start the simulator.
If I go back to the rendering options and uncheck the 3D clouds before exiting, everything is peachy and perfect the next flight. If I accidently start FGFS after having exited with the 3D clouds enabled and it looks bad I can open the rendering options and uncheck 3D clouds, exit the simulator, and then restart it and it starts just fine.
None of the other options causes this problem...it is confined to exiting with "enable 3D clouds" checked after a flight.
Thanks to everyone for the help and please keep up the great work1
Brian
