Hi,

I think I have encountered with a bug in FindShortestPath. EdgeWeight
specified in Property is not recognized.

In[32]:= $Version
Out[32]= 9.0 for Microsoft Windows (32-bit) (November 20, 2012)

In[10]:= FindShortestPath[Graph@
{Property[1\[DirectedEdge]3,EdgeWeight->100],Property[1\[DirectedEdge]2,EdgeWeight->2],Property[2\[DirectedEdge]3,EdgeWeight->3]},1,3]
Out[10]= {1,3}

In[30]:=
FindShortestPath[Graph[{1\[DirectedEdge]3,1\[DirectedEdge]2,2\[DirectedEdge]3},EdgeWeight->{100,2,3}],1,3]
Out[30]= {1,2,3}

-- 
Best Regards,
Li Zhengji
