Subject: Locators and Appearance

Hello all,

this one works. I get three different Locators named a, b, c:

Manipulate[Graphics[{Opacity[.2], Polygon[pts]}, PlotRange -> 1.2],
{{q[1], .5, "L1"}, -1, 1}, {{q[2], -0.3, "L2"}, -1, 1},
{{q[3], 0.8, "L3"}, -1, 1}, {{pts, {{-.5, 0}, {1, 0}, {0, 1}}},
Locator, Appearance -> {a, b, c}},
TrackedSymbols :> {pts}]

This one does not work properly:

Manipulate[Graphics[{Opacity[.2], Polygon[pts]}, PlotRange -> 1.2],
{{q[1], .5, "L1"}, -1, 1}, {{q[2], -0.3, "L2"}, -1, 1},
{{q[3], 0.8, "L3"}, -1, 1}, {{pts, {{-.5, 0}, {1, 0}, {0, 1}}},
Locator, Appearance -> {q[1], q[2], q[3]}},
TrackedSymbols :> {pts}]

Thanks for any advice.
