From: S. B. Gray on 11 Aug 2010 04:47 Sometimes (not yet well-defined) I try to stop a loop, (either because it's running some wrong code or because the loop will take days or hours) with alt-comma but it keeps going. More than once I have had to shut the whole system off. Granted, Microsoft does not provide a competent universal interrupt (which the 35-year-old Tops-10 did very nicely) but maybe Mathematica can be modified to stop more easily. ?? Is anyone else bummed by this? Steve Gray

Alternatively, you can create a batch script containing one or both of: taskkill.exe /im MathKernel.exe /t /f taskkill.exe /im MathKernel.exe /t /f David Bailey http://www.dbaileyconsultancy.co.uk
From: Sjoerd C. de Vries on 12 Aug 2010 05:28 You better try alt-period (abort) instead of alt-comma (interrupt). I find that this works better if I use the left alt button instead of the alt button for some reason. Your milage may vary. Sometimes using the same function in the Evaluation menu helps. Otherwise, just kill the kernel (not the front-end) either in the Evaluation menu or the task manager. Cheers -- Sjoerd On Aug 11, 10:47 am, "S. B.

On the Mac at least, I can usually cut off a running calculation by quitting the kernel (using the pull down menu). When this fails, I can force quit Mathematica from the OS. I don't know if there is an equivalent action on windows. I never had to shut down the whole computer because I couldn't stop Mathematica. Themis |
