It looks like a bug to me.
You could plot the points separately. In Presentations this would be:
Needs["Presentations`Master`"]
f[x_] := x^3/3 - x;
Draw2D[
{Draw[f[x], {x, -3, 3}],
PointSize[Medium],
Point[{#, f[#]}] & /@ {-1, 1.5, 0, 2}},
Axes -> True]
Or use Plot with Epilog to plot the points.

Hello,
I have a parasite Meshpoint (at about x=2.2) with the following input:
Plot[(1/3)*x^3 - x, {x, -3, 3}, Mesh -> {{-1, 1.5, 0, 2}}, MeshStyle ->
PointSize[Medium]]
As I have often these parasits, I really wonder... Can somebody help and say
how I can delete it?
Regards,
F.Jaccard
