Thanks for the input.  It convinced me to keep looking for the problem.  It
turns out that the routine XPLOT3D.PRO uses the following line to add the
model to the view.

    Oview2 -> setproperty, subject = Omodel

which appears to be the same as:

    Oview2 -> add, Omodel, /alias

When I replaced the line with simply:

    Oview2 -> add, Omodel

Pickdata worked fine.

Thanks,
