It works fine the first time I hit the Save Through Ajax button. But after that, it says "Draft saved at 4:22:23 pm. Last edited by XXXX XXXX on June 17, 2011 at 4:21 PM" and the button doesn't reappear until I reload the page or hit the Save Draft or Publish buttons. I thought it would reappear after the auto-save time had elapsed, but that didn't happen either. Also, it doesn't seem to save the post even after the auto-save time has elapsed.
