Hi Burt,
I have now protected the drawing function TPolyMarker3D::PaintH3
in case of histograms with a very large number of entries.
The new algorithm will never plot more than kMaxEntry(100000) markers.
If an histogram with more entries is found, the number of points is scaled
to the maximum kMaxEntry.
Thanks for reporting this case.
Meanwhile, you can use
foo->Draw("box")
instead of
foo->Draw()
