I am using the most recently updated version of Secondlife, not a third party viewer. I just installed it recently. I am running Macintosh 10.9.3. Litterally all drop-down items do not function. I see the button depress, but no items are revealed to me. None of them at the top of the viewer, none of them in the preferences, and none of them in any profiles. I require advice. What more information would be helpful? Clearing the cache and reinstalling are not solutions.
