I tried it also on 5.1 in Windows98 and it also crashed there. It does not
crash if there is a complete cycle. The following works properly in 5.1 and
5.2.
Needs["DiscreteMath`GraphPlot`"];
GraphPlot[{1 -> 2, 2 -> 3, 3 -> 4, 4 -> 5, 5 -> 6, 6 -> 7, 7 -> 8, 8 -> 1},
EdgeStyleFunction -> (Arrow[{#1, #2}] &)];
The following crashes in both versions.
GraphPlot[{1 -> 2, 2 -> 3, 3 -> 4, 4 -> 5, 5 -> 6, 6 -> 7, 7 -> 8},
EdgeStyleFunction -> (Arrow[{#1, #2}] &)];
I wonder if anyone else with Windows has this problem?

Everything works without a glitch here, but I only have:
$Version
5.1 for Mac OS X (October 25, 2004)
