One more thing we've noticed which seems to have been there since even before 3.0.11: With 'mangled names = yes', if you double-click an object in XP called 'susprod_notify.reg' the confirmation prompt shows: "Are you sure you want to add the information in J:\S8FQAP~T.REG to the registry?" With 'mangled names = no', it appears correctly, but of course DOS can no longer see the LFN objects.
Created attachment 1389 [details] log level 10 of regedit up to confirm prompt
I get the same behavior in regedit importing a file on a local NTFS drive.
