--- Comment #1 from Michał "phoe" Herda phoe@openmailbox.org --- More details:
START actually seems to work, EXCEPT when the title is provided in the beginning (which seems obligatory if I want to quote the EXE path, for example, in case of spaces) and the title is empty, namely, ""
A command like start "foo" C:\Furcadia\Furcadia.exe launches the program properly.
