Crinkled Hyperbola (ContourPlot in Manipulate)

Re Mathematica 6.0 under WinXP.

As the slider moves, a point glides along the hyperbola:  

Manipulate[ContourPlot[x^2-y^2==1,{x,-3,3},{y,-3,3},Epilog->{
PointSize at 0.02,Point@{Cosh@h,Sinh@h}}],
{h,-1.5,1.5}]

However, the moving point crinkles the plot, which restores itself when the mouse button is released.

What causes the crinkling (this seems tied to ContourPlot, since no crinkling occurs when I use Plot[Sqrt[x^2-1],...])?

Thankx.

Bruce
