Happy to oblige and in the process of doing so, discovered the problem (the code below now works).  

The culprit was that the option CenteredGraphicDisplayFunction (now in Show) had been used in ShowGraph (this option had worked for an earlier application in which the graphics stood alone).  This nonstandard option is implemented from code received a few years ago from Tech Support.



$TextStyle = {FontFamily -> "Arial"};

g = FromOrderedPairs[{{1, 2}, {1, 3}, {1,
 4}, {2, 4}, {3, 4}, {4, 3}}, Type -> Directed]; 

X = {{0, 1, 1, 1}, {0, 0, 0, 1}, {0, 0, 0, 1}, {0, 0, 1, 0}};

g2 = Graphics@Text[MatrixForm@MatrixForm@X, {0, 0}];

g1 = ShowGraph[g, 
    VertexNumber  -> On, VertexNumberPosition -> {.1, 0}, PlotRange -> 
        All, ImageSize -> 200, DisplayFunction -> Identity];

Show[GraphicsArray@{g1, g2}, DisplayFunction -> CenteredGraphicDisplayFunction];

Why don't you give us a complete specific example so that we don't have to
make one up? That increases the change of obtaining an answer.

Re Mathematica under WinXP.

Let G1 be a (Combinatorica) Graph object (e.g., G1 = FromOrderedPairs[...]).

Let G2 be any Graphics object, e.g., G2 = Graphics[...].

I want to display G1 and G2 side-by-side via Show@GraphicsArray@{G1, G2},
but can't figure it out:

- G1 isn't a Graphics object (and so my command fails).

- I can display G1 via G3 = ShowGraph@G1, but then Show@GraphicsArray@{G3,
G2} fails (G3 is a symbol).

- Hoping to piece together a Graphics object from FullGraphics@G1, I am
stumped by the embedded Rule object.

Any ideas on how to display these two objects in an array?
