--- Comment #23 from Paul Vriens Paul.Vriens.Wine@gmail.com 2009-01-26 03:32:57 --- One other thing I found (but that's actually the opposite of what we are trying to show/fix) is that Wine gives DRIVE_NO_ROOT_DIR with GetDriveType if we have an unmounted CD whereas Windows returns DRIVE_CDROM regardless whether there is a CD mounted or not.
I'm trying to come up with a test for our test suite that shows the above behavior (and maybe even a fix).
