RE: Re: GraphPlot display anomaly

Whenever I try to evaluate that statement, or the original posters
statement, or any GraphPlot statement that doesn't have a complete cycle, my
Mathematica 5.2 crashes!

For example, the following statement that deletes a number of edges from the
example in Help crashes.

Needs["DiscreteMath`GraphPlot`"];

GraphPlot[{1 -> 2, 2 -> 3, 3 -> 4, 4 -> 5, 5 -> 6, 6 -> 7, 7 -> 8},
    EdgeStyleFunction -> (Arrow[{#1, #2}] &)];

crash!

The only problem is with your code. The correct way to do this is:


Needs["DiscreteMath`GraphPlot`"];


GraphPlot[{1 -> 2},
     ImageSize -> {50, 50},
     DisplayFunction -> (Display[$Display, #] &)
     ];

Note the crucial parentheses missing from original code.
I think the answers to all your questions should now be self-evident.
