David, I'm still looking into your NWX problems. I have your changes to use the earth radius from the AREA file. I will work with Tom Yoksas to determine the impact of the AREA file parameters, and have sent your message on to NCEP for the developers there to consider. I made a fix to gpfront from 5.6 to 5.6A that fixed a bug in the H/L symbol plotting since the spcl marker numbers were changed from 5.4 to 5.6 (so you would have seen circles plotted instead of the H and L symbols in 5.6. Harry mentioned that you were having a problem with display to remote systems in particular with 5.6, so I'm still investigating that.
