issues with GraphPlot

Hello group, A few things that I just can't figure out. 1. EdgeRenderingFunction ignores edge labels. GraphPlot[{{"B" -> "A" , "+"}, {"A" -> "B", "+"}}, DirectedEdges -> True, VertexLabeling -> True, VertexRenderingFunction -> ({White, EdgeForm[Black], Disk[#, .05], Black, Text[#2, #1]} &), EdgeLabeling -> True, EdgeRenderingFunction -> ({ Arrowheads[Medium], Arrow[#1 , 0.07]} &), PlotStyle -> Thickness[0.005]] 2. As it is, above code produces a graph that is stretched horizontally a bit too much. About the half the horizontal width works better for me. How do I accomplish that? AspectRatio-> 1/GoldenRatio doesn't work since disk gets stretch also. 3. For node A to appear on the left, "B"-> "A" has to be defined first. If I reverse it, then the node B will appear on the left. What is the reason for this? Thanks in advance for any info. Sean
