Thanks everyone for your help.
I was trying to plot too many points. Cutting down solved the problem:

SetDirectory["c:\Documents and Settings\P. Lindsay\DESKTOP\alanr"];
t=Table[ReadList["alan3.txt",Number,RecordLists -> True]];

ScatterPlot3D[t,BoxRatios->{10,10,10},Axes->True,
  AxesLabel->{"fair","num","ratio"},ViewPoint->{3.0,2.5,0.3}]



However.... I now have a nice ScatterPlot3D; how do I get a surface plot ?

Thanks again for your patience and contributions,

best wishes,

Peter Lindsay
