OK...the MD5 Hash for 1.5.0.5 + Enigmail/GPG on the download page for 1.5.0.5 does *not* match the MD5 hash I get when I crunch it. The hash, as it appears on the page is:
cbfe358b220b8960ccd3e20a8733e736
...and the hash, as I calculate it, is:
34cc751a77c20fbc582844629fdf6c77
I did a search on this and found nothing. And yes, I'm one of the "geek squad" who checks things like this, but it's only because I'm paranoid. 
Can anybody confirm, and if the maintainer happens to read this (hi, John!) can you please verify the correct MD5 sum?
I've just newly found this site after purchasing a U3 flash drive (didn't mean to), and I absolutely love the PortableApps.com model over the U3 model.
