I was using Mathematica to solve simultaneously the x and y equations
of motion for a particle subjected to a Yukawa potential.  NDSolve
predictably gave an interpolating function.  However, when I tried to
plot this function, I got the error message that it is not real valued
at certain pairs of points.  What is going on?  Can I do anything to
remedy the situation?  


Thanks.
