Re: GraphPlot display anomaly

What is the problem here?

Needs["DiscreteMath`GraphPlot`"];

loads the package which provides the GraphPlot-function. Issuing the
command

>> GraphPlot[{1 -> 2}, ImageSize -> {50, 50}];

yields a plot of a line, while

>> GraphPlot[{1 -> 2}, ImageSize -> {50, 50}, DisplayFunction -> Identity];

suppresses the plot -- just like one would expect.

At the end maybe I should note that this all works in

>> $Version
>> 5.2 for Linux (June 20, 2005)
