I don't understand why I have these problems, because none of the reviews mention anything at all similar to these things.

None of the reviews mentioned anything like that because they didn't happen to the reviewers. As a member of the FD4 test team, I did have some glitches in some of the beta releases, but they were identified and corrected before release.
Flight Deck 4 is one of Abacus' best sellers, and problems like yours are not the norm. I seriously suggest that you e-mail Abacus Tech Support on this - presuming you did get FD4 from a reputable outlet.
