I have been using encrypted disk images as a back-up destination with SD! on Panther and Tiger for quite some time.

I have just attempted my first similar back-up under Snow Leopard.
SD! appears to hang at the point that the destination image should be mounted.

In my past experience, there will be a prompt to enter the password for the image as it is being mounted by SD! (since it is not stored in the keychain).

No such prompt is occurring here.

(Adding the password to the keychain allows SD! to proceed, however I would prefer not to use the keychain and would rather be promoted to enter the PW manually as had been the case)
