Now the Favorites tab in Materials is empty, and i cannot add to it all the materials that were in it before.&nbsp; I am using a modified version of the Default project (just added sub work space folders). Please help.&nbsp; Will provide additional information if required.</P> Wed, 15 Apr 2015 15:12:31 GMT Anonymous 2015-04-15T15:12:31Z
