When the mouse pointer passes over the Locator graphic (or one clicks at any point in the frame), the underlying equation that generates the ContourPlot is visible in a text box. How can I suppress this output? Here is the code.
Manipulate[ iv = Row[{"t0 = " , N[p[[1]], 3], ", ", "x0 = " , N[p[[1]], 3]}]; ContourPlot[(x - t - 1) Exp[x - p[[2]]] == p[[2]] - p[[1]] - 1, {t, -6, 6}, {x, -6, 6}, PerformanceGoal -> "Quality", BaseStyle -> {FontSize -> 14}, FrameLabel -> {t, x}, RotateLabel -> False, ContourStyle -> Directive[Red, Thick], Epilog -> {Point[p], Text[iv]} ], {{p, {-2, -2}}, {-10, -10}, {10, 10}, Locator, Appearance -> Graphics[{Blue, Disk[{0, 0}, .1]}, ImageSize -> 14]}]
