I think this has the same cause as the problem with & in a file name on
Windows reported in http://seclists.org/nmap-dev/2009/q3/0604.html,
namely, that on Windows the Nmap subprocess is spawned with shell = True.
This done to avoid having a terminal window open every time you run a
scan in Zenmap, but as a side effect it means that when the subprocess
is killed, it only kills the shell and not the nmap process that is
running in the shell.

Does someone have an idea of how to solve this? Is there a Python way to
run a terminal program without opening a terminal window? To see what I
mean, edit zenmapCore/NmapCommand.py and change the line

shell_state = (sys.platform == "win32")

to

shell_state = True
