--- Comment #5 from Vincent Povirk madewokherd@gmail.com 2008-05-19 17:55:21 --- I don't think so. The .lnk files has the arguments without double quotes so the .desktop file should treat the different parts of the filename as separate arguments. It would be impossible for Wine to determine the semantics involved.
And I've just tried putting the whole thing in double-quotes using the shell. The program did not start.
