I've installed A3 on two computers and have yet to have it complete indexing. Left one computer on over the weekend, no good. Started it up again this morning, it currently says 72:30 remaining. Indexer log shows activity, though some items take far longer than expected, such as:
11/16/2009 10:10:59 | INFO | 5 | LibraryIndex | (Timed) Indexing LLS:APOCNTHONE
11/16/2009 13:13:23 | INFO | 5 | LibraryIndex | (3h 2m 24s) Indexing LLS:APOCNTHONE
Previous Alpha builds indexed successfully. No such luck with A3 for me.
