OK, for your further testing please use only the older cygwin1.dll from JtR distribution. > Solar provided me with 2 tar balls to compile, one with fork the other > without Actually, the newer version simply has --fork disabled on Cygwin by default, but you may trivially re-enable it in os.h - I thought you would. > (both severely limited formats to choose from).

For your testing, please set "Save = 10" in john.conf - then you'll expect pot and log file updates every 10 seconds. (By default it's every 10 minutes.)
