I don't know what you are talking about with your point #2. I get exactly
the same 3-d plots in both the DOS and PM versions, a 3-d parabola. Are
you sure you are not playing with the x and y-ranges before the plot.

In any case, the latest GnuPltPm does not exhibit the behaviour you
describe concerning 3-d plots. It is slower, and the ``porter'' has
pointed out that this is due to the DOS version writing directly to
hardware, and the PM version not. I hope he has oodles of free time
in the near future to do us all a service.
