Makes sense, but that's not it, unfortunately. I tried it and it still hangs...
Also, strangely, with the two "\n"s, the next time I try to write to the filehandle it says the pipe is broken. Here's sample output from the tool: ************************************** ralph 2104% yprtool -l 90 0 0 50 50 50 <- I type this 130.000000 -50.000000 -130.000000 <- it outputs this 40 40 40 <- I type this 140.000000 -40.000000 -140.000000 <- it outputs this <- I type a return ERROR: Wrong number of inputs in stream. <- and it complains Throwing exception (1: "1") at ../src/YprTool.cpp line 192.
