Hi,

I am looking the GraphPlot notebook in the Add-ons & Links ->  
Standard Packages -> DiscrateMath Help section and I am trying to  
execute the very first two lines of the notebook:

In[1]:=
<< "DiscreteMath`GraphPlot`"


In[2]:=
GraphPlot[{1 -> 2, 2 -> 3,
     3 -> 4, 4 -> 5, 5 -> 6,
     6 -> 7, 7 -> 8, 8 -> 1,
     1 -> 9, 2 -> 9, 3 -> 10,
     4 -> 10, 6 -> 11,
     5 -> 11, 7 -> 12,
     8 -> 12},
    EdgeStyleFunction ->
     (Arrow[{#1, #2}] & )];
 From In[2]:=
Show[Graphics[{

}], AspectRatio->1,
PlotRange->{{47, 335}, {4, 292}},
ImageSize->{288, 288}]


The output appears to me as a straight line from the middle of the  
rectangle to the upper right corner.  I am wondering if it is just my  
machine or others can see also just a line.

In[12]:=
$Version

"5.2 for Mac OS X (64 bit) \
(June 20, 2005)"

     Hardware Overview:

       Machine Name: Power Mac G5
       Machine Model: PowerMac11,2
       CPU Type: PowerPC G5 (1.0)
       Number Of CPUs: 2
       CPU Speed: 2 GHz
       L2 Cache (per CPU): 1 MB
       Memory: 2 GB
       Bus Speed: 1 GHz
       Boot ROM Version: 5.2.7f1
       System Version: Mac OS X Server 10.4.6 (8I116)

Thanks ahead,

János
P.S.  Wolfram Support sent me another GraphPlot.m, but the result is  
the same.  /Above was done with new GraphPlot.m/.  The machine is a  
Dual Core PowerPc G5.  GraphPlot used to work perfectly on my earlier  
machine, a 1.25Ghz G4 with 32-bit Mathematica 5.1.
