             Bug #: 5596
           Summary: Kepler UI freezes after Login Anonymously
    Classification: Unclassified
           Product: Kepler
           Version: 2.3.0
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: P2
         Component: general
        AssignedTo: barseghian at nceas.ucsb.edu
        ReportedBy: jones at nceas.ucsb.edu
         QAContact: kepler-dev at kepler-project.org


When a user has a remote repository configured for actor searching, they are
prompted to login to search for a component.  Clicking Login Anonymously causes
Kepler's user interface to stop responding to user input.  Some users at a demo
interpreted this as Kepler freezing, and so killed the Kepler process.  I tried
this, and the login eventually completes and Kepler becomes responsive again. 
But there is no indication in the UI that we are waiting for the login to
complete, and so this is easily confused with a crash of the program.  Two
potential solutions:

1) Make login much faster, on the order of subsecond
2) Provide a UI indicator that we are waiting for login to complete, such as a
progress meter
