Nevermind, I figured it out.
Now another strange issue.
Compare the following two codes and look at the location of the edges
for the top edge.
GraphPlot[{{"B" -> "A", "( c2 + )"}, {"A" -> "B", "( c1 + )"}},
DirectedEdges -> True, VertexLabeling -> True,
VertexRenderingFunction -> ({White, EdgeForm[Black], Disk[#, .05],
Black, Text[#2, #1]} &), EdgeLabeling -> True,
EdgeRenderingFunction -> ({Arrowheads[Medium], Arrow[#1, 0.1],
Inset[Text[#3], Mean[#1], Background -> White]} &),
PlotStyle -> Thickness[0.005]]
GraphPlot[{{"B" -> "A", "( c2 + )"}, {"A" -> "B", "( c1 + )"}},
DirectedEdges -> True, VertexLabeling -> True,
VertexRenderingFunction -> ({White, EdgeForm[Black], Disk[#, .05],
Black, Text[#2, #1]} &), EdgeLabeling -> True,
PlotStyle -> Thickness[0.005]]
What expains the lowering of the top label in the top code?
