The installation still completes. When I open my database and try to fetch a new entry using Google Scholar, I can see the entry in the preview window, but when the go to the next window which generates the key, the window is blank. Here is a screenshot.

• Installation problems on Mac OSX should be solved in version 3.5 of JabRef. See http://www.jabref.org/blog/
• About Google Scholar, there is an issue with version 3.5 (and perhaps earlier versions). See: Jabref websearch: Google Scholar shows no results on second pop-up menu #1639. This bug should be fixed in the development version, which you can find here: http://builds.jabref.org/master/
