After downloading resource patches, Indexer.log file shows:
03/18/2011 23:40:49 | INFO | 2 | IndexerProgram | Setting Require Discovery.
03/18/2011 23:40:49 | INFO | 2 | ResourceManager | Discovery requested: 2011-03-19T05:40:49Z
Menu Bar status is stuck at 99 %

Observation: using Logos as second user on iMac - same situation for both users - clicked cancel downloading - started resource discovery and indexing.
Keep Smiling [:)]
