@Szabolcs Could you write something down in the answers section so that I can mark this question as answered?

It works! I have always assumed that clicking on the "x" button is equivalent to "Quit" (or Ctrl-Q) from the pull-down menu. From now on I will use the Ctrl-Q shortcut.

comment Producing a bar chart with height and color determined by two distinct lists
@Brett Thank you for the simple solution. I was working with ChartElementFunction, not realizing that ChartStyle is the option I ought to be using. I just could not get rid of the gaps between successive rectangles when I used ChartElementFunction.

comment Differential geometry add-ons for Mathematica
If you are trying to do tensor calculations, you may want to look at John Lee's Ricci package. He also mentions the commercial package MathTensor on that page.

@J.M. I am amazed at how quickly you come up with such elegant codes.

comment Using implicit differentiation to find a line that is tangent to a curve at a point
What is a good way to take the derivative of a function so that the output is also a function? It would be nice if I could do something like D[g,x][1,1,1] and get the partial derivative evaluated at $(1,1,1)$. Using ReplaceAll just does not seem right.

comment Using results of Reduce
@rcollyer Thanks for editing my answer. I was so excited that I could finally contribute something that it did not occur to me to provide links or use the code block.
