If the new synaptic gets interrupted during an apply session, if you choose 'no' in the popup,
to make re-applying possible, it crashes, instead of going back to the main screen. Your selections
are gone. No big deal when doing a 'mark all upgrades' session, but irritating if you were
installing a new selection of apps, like a dozen camera/photo apps for example.
The apps downloaded before the interruption do remain in the cache, and once you sort
out your selection again, the downloads pick up where needed.
