GraphPlot display anomaly

Hi All,

try the followings with Mathematica 5.2:


Needs["DiscreteMath`GraphPlot`"];

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


Q1. Why does it produce two output graphics?
Q2. Why does it not work without Evaluate[...]?
Q3. Why does it work with simply using  DisplayFunction ->
$DisplayFunction?

May it be that the implementation of option-passing was screwed up in
DiscreteMath`Graphplot?

Thanks,

Istvan Zachar
