Okay, then yes I misunderstood you. I mostly agree but it's also been 17 years and what are the odds that the offending code still exists? What are the odds that it's TB's fault?

I know people report the issue but googling I can find similar complaints across all major mail clients.

I just don't think there's enough information to make strong conclusions and I don't think California cancer warning labels work. I think they teach people to ignore warnings instead.
