Check how you're getting that $workSpace variable. Maya on windows uses
unix-style ('/') directory delimiters internaly, rather than ms-dos
style escape characters ('\') - and if you pass a unix path through to a
DOS comand, it's going to think you're setting bad options. The
'toNativePath' command should sort you out.
Last time I used 'start' I think I had to double-escape the DOS
delimiters to get them passed through ok:
syetem( "start C:\\\\PROGRA~1\\\\BLAH.EXE" );
rather than just
system( "C:\\PROGRA~1\\BLAH.EXE 2>NUL" );
could be wrong though - that was some time ago.
