So I bring up the post box, getting ready for an entry. Get a call, go get coffee, and don't make it back for 10 minutes or so.
I write up the tidbit, hit publish, and instead of publishing it, it asks if "I'm Sure" I want to save this post.
So I hit the back button, copy the post text, and click on write post again. Add in the text, tag it, name it, and publish it.
I thought I was going loopy. However, I tried it again, and again, and again.
What I narrowed it down to is the auto-save.
If there isn't anything to save, and it tries to auto-save, it produces an empty post id.
As a note, the post is lost if you publish it, and answer yes. You're also stuck on that screen.
