[pstricks] strange line placement

[Zbigniew Nitecki]

This code:
***********************
	\begin{pspicture}(-1.5,-0.5)(1.5,3)
		\pstThreeDCoor[xMin=0, xMax=1.5, yMin=0, yMax=1.5, zMin=0, zMax=3]
		\pstThreeDLine[linestyle=dashed, arrows=->](-2.0,2.0,1.0) 
(-0.7,0.7,1.0)
		\pstThreeDPut(-2,2,1){$x^{2}+y^{2}=1$}
	\end{pspicture}
***************************
produces this:

Why do the endpoints of the line not match the placement of the text?
