This is true also for the "one user system only" mode (dasBlog 2.0.7226.0); If the post date is in the future (somehow due to a bug or by setting the post date), there is only the way to use the events display to navigate to/change the newly posted entry.
Think, a page displaying just the saved, but not yet published entries would be cool.
