According to Microsoft's documentation
(http://msdn.microsoft.com/en-us/library/96ayss4b.aspx) : "If used in
a Windows program, the _popen function returns an invalid file pointer
that causes the program to stop responding indefinitely. _popen works
properly in a console application.", so it shouldn't work in a GUI
application.
