Up until version 2.5 it couldn't decode the thumbnail files but that issue has been partially resolved in the 2.6 version .... however it still has issues sometimes when decoding large thumbnail caches. Still makes it worthy of adding to my portable collection though. Thanks for the heads up regarding the new version.
