Hello all out there I use Mathematica 4.2 under FreeBSD (Linux API) and 4.1 (Linux). I want to demonstrate my students something about grad, div and curl. So I prepared a notebook on the FreeBSD-machine (Mathematica 4.2), which worked there OK. Now I want to re-evaluate the notebook at the university (Mathematica 4.1 on Linux) and I get the following: -----8<----------8<----------8<----------8<----------8<----------8<----- In[1]:= << CalculusVectorAnalysis Cartesian::"shdw": Symbol "Cartesian" appears in multiple contexts \ CalculusVectorAnalysis, Global definitions in context \ CalculusVectorAnalysis may shadow or be shadowed by other \ definitions. In[2]:= <<GraphicsPlotField3D <<GraphicsPlotField <<GraphicsContourPlot3D <<GraphicsLegend In[3]:= SetCoordinates[Cartesian[x, y, z]] Coordinates::"invalid": Cartesian[x, y, z] is not a valid \ coordinate system specification. Out[3]:= SetCoordinates[Cartesian[x, y, z]] -----8<----------8<----------8<----------8<----------8<----------8<----- At this point I can stop evaluating the notebook. :-( But what is the problem here? Is there a significant difference between 4.1 and 4.2? A Bug? Does a workaround exist? (I don't want to update/downgrade to have both machines at a consistent level) I couldn't find anything with google (but maybe I didn't look at the right places -> pointer to them might be enough). Thanx for any help,
