I am using arara and TexStudio, and before I started using arara, Texstudio would shut down the pdflatex process on hitting Stop Compiling. I'm using arara with the following commands:
% arara: pdflatex % arara: biber % arara: pdflatex
Whenever there's an error, I have to shut down the pdflatex process manually from the Task-Manager, since Stop Compiling won't shut down the process anymore when I use arara.
(I'm not using the English version of TexStudio, so I'm not entirely sure that what I'm hitting is called Stop Compiling. It's a big red square that tells TexStudio to stop compiling.)
