Just a heads up,
I removed my install (which I installed from the tar.gz that was provided in the first post, and instead grabbed the SVN : Checked out revision 78259
I made sure to flush from the front side and admin side before I did a db/build and for good measure, I ran it twice :)
And of course when I went to add a field -- it worked! :)
I'm toying with it now... can't wait to see what's new
Thanks so much for your contributions.
