comment Show path with arrows in a matrix
I see. Because there is no edge between 4 and 6 above. No, I am using V8.0.0.

Looks like I cannot do GridGraph[{5, 5}, VertexSize -> Small, GraphHighlight -> {1 \[UndirectedEdge] 2, 2 \[UndirectedEdge] 3, 3 \[UndirectedEdge] 4, 4 \[UndirectedEdge] 6}] because the last 6 is larger than the dimension 5.

It is very strange here. I can sometimes get the command GridGraph[{5, 5}, VertexSize -> Small, GraphHighlight -> {3 \[UndirectedEdge] 4, 3 \[UndirectedEdge] 2, 2}] executed, but not other times. What is going on here?

I got an error GridGraph::optx: "Unknown option EdgeStyle->Dashing[{Small,Small}] in ". What version of Mma are you using? Thanks!

@Szabolcs: no it is not assignment. It is different from that question; here, I need arrows.
