The developer promised that those problems will be fixed in the next (RC1 ?) version.
Nevertheless I'd still prefer a splitting between the possibilities to (re)build the file cache and the quick system analysis, i.e. the possibility to run them separately.
Those two things melted toghether might be confusing for beginners: how should they know the quick system analysis is also building a (new) cache, in other words that they have to run the quick analysis to build a new cache?
It looks like that pair of concepts doesn't cover each other...
