Hello,
finally, i tested pd-0.48-0test5b.msw (windows 8.1) and on my computer it seems that pd~ (subprocess) doesn't work. (it works on pd 0.47.1)
opening file extra/pd~/pd~-help.pd OK
starting the subprocess OK
pd-subprocess receives messages (foo bar baz( from main process OK
but
in pd~-help) makes the subprocess crash and the main process freeze
pd~-help.pd doesnt receive subprocess messagse [a b c( etc...
sending signal from subprocess to main process (by checking the boxes
below [osc~ 440] in pd~-subprocess) create erratic values in main process (1.#INF or 1.QNAN after [env~ 8192] box)
