Can someone confirm that the subject-line version of MacMolPlt for Windows (v7.7) works fine with the FF v.6.2.0 files? MacMolPlt will show some higher-energy occupied MO and will stay stuck there; no change is possible.
What can cause this specific problem?
EDIT: Per OP's suggestion, I found a recent (Sep. 2016) version of Molden (a compiled native Windows version) that works beautifully. It can be found at ftp://ftp.cmbi.ru.nl/pub/molgraph/molden/bin/Windows/
