OK, I'm running LW2.9.11 on OS10.2.6 and I have not seen any increase in the number of files flagged as corrupted. Whenever I see the warning, I always continue to the end and test the quality of the download. As we are always dealing with old copyright-free material, there can be many "faults" in the quality of the recordings. Hence, I take a pragmatic view. During my period of Limewire use, I think I have discarded about a dozen as "this would drive me insane if I tried to listen to this again" files. The vast majority of those flagged have only a few minor blemishes. Those which have more intrusive faults, I remove from the sharing folder to prevent spreading the "problem" further downstream (we all do that, don't we?!?). The others I leave for others to share (sorry about that but, since folks are getting what I offer without payment, they cannot expect the same uniformly high quality as from a purchased product, now can they?!?).
