I just installed gramps 4.0.2 on Windows 7 x64 and it works well.  I added a couple of people but noticed that I can't add a middle name.  I am also unsure what to do about maiden names.  Should I add the person with their maiden name?  Would I add a name change event?  Also there is a bug when I try to add an event, the events don't scroll.  There is a long list of events that go off the screen so I can't select marriage.  I read the online documentation for version 4.0 but it doesn't answer either question.
