Hello everyone.

I am having a somewhat minor but fairly horrible problem using troff
and MM macros.  The problem is concerned with floating displays.  Any
insights you may have would be most welcome (please respond via e-mail).

The problem is this.  I am using floating displays, via .DF, to ensure
that figures in my document are positioned neatly at the top of a page,
and there are not large chunks of blank space at the bottom of many
pages, as the would be if I used a simple .DS command.  Now, in order
to ensure that the caption for the picture or whatever is associated
with the correct figure, the .FG command is placed inside the .DF/.DE
pair.  All is okay so far.  The kicker is that, if I have some "pic"
specifications in my figure, I have to use ".DF CB" in order to get a
result that is centered on the page.  But, this blows the centering of
the caption all over the place.  Usually, the left part of the caption
is aligned with the leftmost item of the picture.

Maybe a diagram would help:

I start off with:

	.DF CB
	.PS
	some
	pic
	stuff
	.PE
	.FG "title"
	.DE

and I want:


			  a
		        pretty
		       centered 
		       picture


		     FIGURE X  title

but I get:
			  a
		        pretty
		       centered 
		       picture


		       FIGURE X  title


See how the caption is moved over?  Usually, my diagrams are such that
the caption is over way to far to the left, but I hope that you get the
idea.

Any clues?
