Logic crashes when selection "Save as, Save as copy or quit

Logic crashes when I select Save as , Save as copy or if I try to quit the project . There is no selection box to that give me the option it just crashes . Logic loads excellent and it record it suppose to but again when I Name and save my project it crashes . I have reinstalled my operation several times that is not the problem. My other programs work good (Protools and Ableton). It is also affecting MainStage, Waveburner and Soundtrack Pro these programs wont save projects.
