 Sep 9 comment Changing BarLegend border style I tried this in V10 running on OS X -- didn't work. Sep 9 comment How do you turn off the Dashed graphics directive? I reported the behavior of Dashed in ListPlot to WRI tech support, and in their reply they agreed it was a bug. Should the question, therefore, be tagged with the bugs tag? Sep 8 comment Mathematica not responding The first thing I would try is changing u3L[x3, x1] := Evaluate[InverseFourierTransform[u3T[x3], xi, x1]]; u3[x3, x1, t] := Evaluate[InverseLaplaceTransform[u3L[x3, x1], s, t]]; to u3L[x3, x1] = Evaluate[InverseFourierTransform[u3T[x3], xi, x1]]; u3[x3, x1, t] = Evaluate[InverseLaplaceTransform[u3L[x3, x1], s, t]];. That is, use Set rather than SetDelayed in the definitions of u3L and u3. Sep 8 reviewed Leave Open Show graphics content in front of frame Sep 8 comment How do I feed data points into an equation to solve NUMERICALLY? Using your equations and Solve and Eliminate, I get a symbolic solution for y as a function of x very quickly. Plotting the symbolic y[x] for 1 <= x <= 5 is also quick. Where are you encountering any slow response from Mathematica? Sep 8 comment How to manipulate with external data? How many is "a lot of triples"? An order of magnitude estimate will do. Sep 8 comment Manipulate in modal mode with data return I think what the OP requests is a bad idea and completely subverts the intended use of dynamic forms such as Manipulate, but it might be possible. My idea is to rig some sort of trigger, conditionally evaluated within the first argument expression of the Manipulate, that deletes the output cell. I'm a little unclear about the "next cell should be evaluated after Manipulate has finished" bit. Not obvious to me which cell qualifies as next :D Joking aside, I say to the OP: you need to tell us much more about what you are trying to accomplish before we can help you. Sep 8 comment Failure to export graphics by right-click when Notebook magnification is changed @Karsten7. OS X. Sep 8 comment SpaceFillingMolecularPlot using CAS number of a compound @user12609. I'm sorry but I don't have an answer to what you ask in the above comment. I recommend you post it as new question. More people will see it that way and you will have a better chance to get an answer.

This may be such a case. Sep 8 comment Failure to export graphics by right-click when Notebook magnification is changed I get these error messages all the time when I save output cells in PNG format. I just ignore them. The PNG files are fine.

Sep 8 comment How can I visualize an array of very small vectors spaced on very large grid? In my opinion this question is not a duplicate. It is not about plotting a 3D vector field. The original title was misleading. I have retitled it with a title I think much more appropriate. I advocate reopening the question.
