My databases are in a sparse bundle, which is password protected. When I open a database in DT3 I am asked for the sparse bundle password, following which the volume is mounted and the database opens.
When I close the database the volume is unmounted (and as such is no longer visible in Finder), but the disk image is not ejected. As such, when I want to re-access the database, the volume is mounted without the password being required. To secure the sparse bundle, I have to open Disk Utility and manually eject the disk image.
This would seem to be inappropriate behaviour, because the unmounted volume is unprotected; I can no longer eject the disk image, because the volume is not visible in Finder after it has been unmounted. This leaves me at risk of leaving the disk image unprotected. DT2 did not unmount the volume on closing the database, and so did not have this problem. Ideally I would like DT3 to eject the disk image rather than unmounting the volume, certainly if the disk image was mounted by an action triggered by DT.
