Why would the frequency of corrupt downloads of images jump so drastically right after Limewire 4.0.6 came out? Curiously the respondent there seems to think it didn't, but it looks like he's outvoted 2-1. Intriguingly, the guy who started that thread also suspects it's the upload code in 4.0.6 that's gone bad, and for more or less the same reasons.
