How can I make a cell that contains an image which can be shifted? i noticed that if you hold Ctrl, a crosshairs appears and you can shoot tiny bullet holes into the cell (they look like points, but i know bullet holes when i see them). and if you right-click copy and paste, you get the {x,y} coordinates of the bullet holes. it looks like some internal EventHandler construction that dynamically updates the ImageMargins. not hard to do yourself if that's all you're after. e.g. Graphics[Disk[], ImageSize -> {50, 50}, ImageMargins -> {Dynamic[MousePosition["CellContentsAbsolute"]] - 25, {0, 0}}]. |

Is it possible to selectively save the calculated values (array) at memory? Regarding the memory issue, take a look at Memory Management |

How to track dynamically generated manipulators? @m_goldberg That's good, I'll add it. I was tryng to keep the examples "minimally general". Funnily, it wouldn't have occured to me to apply Sequence that way. |

Why does this simple program leak memory? What Mathematica version are you using? I know from my own experience doing this exact sort of thing (exporting images) that there is an inexplicable memory issue in my version 8 which didn't occur at all in my V9 trial from the same exact copy-pasted code. |

Why does this simple program leak memory? Have you tried using ParallelDo rather than ParallelMap? I know it shouldn't make a difference, but some of these things are more involved than they seem. Also try just plain Do. Maybe your system is launching like, infinity kernels all of which are running 100 computations, so you may need to specify things like Method -> "EvaluationsPerKernel" -> 1 |

Raster with ColorFunction is blank when Dynamic Updating is disabled it looks like the various Method options ("CoarsestGrained", "EvaluationsPerKernel", etc) have an affect on which plots turn out blank, but they still turn out blank. |
