Sadly, the honeymoon didn't last very long for me.
Drafted a lengthy post today and went to publish it and had problems. Error messages, etc.
And then the look of my blog disappeared in the program, and the drafting page went 'generic.'
I uninstalled, redownloaded, and reinstalled, and could not get the OLW format to sync up with my blog.
When I went to edit the blog account, a lengthy hexadecimal string had replaced my user name.
I don't know what's going on, but I can't get back to where I was when I posted my thank you message.
Help! This was a very short lived victory.
I had trouble with it posting to my blog. I reinstalled the Nightly version and then it worked just fine. I was able to download my theme, and a Category box appeared (it hadn't before). I think they are still working on it. Posts ok for me now.
