 * Common issues
 
 ** Usage on Windows
 
 Multiple users have reported issues when trying to work with =gnuplot.el= on
-Windows. Most notably, the gnuplot process hangs after sending a first line of
-input (this is a common Emacs issue on Windows, see [[https://www.gnu.org/software/emacs/manual/html_mono/efaq-w32.html#Sub_002dprocesses][here]]).

 will unlock it and let you continue). The workaround for now is to make Gnuplot
 output a string before pausing, by doing =pause -1 "Hit return"= or similar.
