Hi Barry,

>Thought I'd let you know about a problem I ran into today while using
>the FRNTDISP command in -XRD 2002. That's version 1.6 of frntdisp.pgm.
>
>I wanted to alert you about it today since I think the problem may occur
>very rarely (i.e., when there's an occluded front in a specific
>orientation). Here's the problem:
>   If your PROJECTION= global keyword in MAP.* is set to MERC (instead
>   of CONF), then FRNTDISP USA doesn't draw today's occluded front
>   running through NY and PA correctly (it omits the round and pointed

>        FRNTDISP: ORINPT DY IS SMALL
>   The other fronts look fine. The problem may be due to the occluded

>   mercator.

OK.  I can replicate the problem by trying to overlay the front
on top of a NY PRO=MERC map for the latest front time.

I don't need these, but thanks anyway.
