--- Comment #6 from Vitaliy Margolen vitaliy-bugzilla@kievinfo.com 2011-11-17 08:37:42 CST --- Mount manager does the right thing - it remove a mount point for an unmounted device. Winecfg is what at fault here. It shouldn't be allowing to use d: drive. Or it should remove device mapping for it (d::).
