Modelworks,
that's a great piece of software! Hashtab. I wonder how I missed it? It's usage is a bit different than I expected though.
It's not really a context menu that it installs. You need to right-click and select the file properties. You'll see that a new tab has been added at the top.
What I really like is that this one shows the hash progress! So I could tell that my system was not stuck!
Thanks!!
