Neil,

Hmm...  This can't have anything to do with the imagery change in the
Unidata-Wisconsin datastream since that had nothing to do with the
front data.

A couple of things that need to be noted:

o the McIDAS applications you are using (DF, SFCPLOT, and FRONT) are being
  sunset in the next release of McIDAS.  ADDE replacements are available
  and are Y2K compatible

o you might want to be more specific in your FRONT invocation:

  FRONT OLAY FRAME GRA=2 LWIDTH=2 2 1 LSIZE=12 6

>The SFCPLOT and FRONT output are telling, but I don't know what.

This may mean that the surface decoding is not working; are your XCD
decoders running?  Are MD files being created?  Can you list data from them?

As far as the FRONT display working, your invocation is asking for the
most current frontal analysis to be put on top of the display.  What you
reall want is for the frontal analysis closest to the display time to
be put up there.  This is what 'FRONT OLAY FRAME' means.

Yes, but are these REDIRECTions active?  Examine the output of:

REDIRECT LIST

Can you do any/all of the following:

SF 1
EG B
MAP NA
FRONT 6
FRONT 12
etc.?
