--- Comment #31 from Louis Lenders xerox.xerox2000x@gmail.com ---
changing
c = strrchrW( volumenameW, '\' );
to
c = strrchrW( volumenameW, '/' );
results in correct volumename being returned and Native Access then works normally.
Hi Stan, just checked but that single change breaks the tests in kernel32/tests so I guess a fix is more complicated then this single change
