Hi Sean,

It is at the installation defaults. In the meantime I realized that although I wanted to plot just one 32x32 frame from a stack of 1000x64, but accidentally I left out the Part designation, so the data was given to ListPlot3D as an 32x32x64x1000 array and that was too much. My apology. However that still should not have cause the Blue Text of Death, Mathematica should have reported back a not enough memory, or malformed data, or any other messages we used to have for these kind of situations.

Thanks a lot for your time, János
