Why does Windows Live Writer do this?

I clicked on the Get Posting Style button when setting up a new blog account in Windows Live Writer. Then I noticed this entry title on my blog page: "Temporary Post Used For Style Detection (c560c898-8ea2-xxxx-xxxx-d25b48d206ed)" What the hell? That is totally stupid. If you're going to post something to my blog and not tell me about it, the least you can do is delete it when you are done. Doh! What if I hadn't noticed it for several days, what an oaf I would look like. That's a bug. Please fix it.
