SharePoint 2010: Designer Workflows won't start

I don't like Sharepoint Designer Workflows, so I never really used them. Lately I had to and it ended in a lot of growing hatred, tears and curses. Boy, do I not like SharePoint Designer. I was finishing up a project and tried to test my Workflows just one more time. They were supposed to start if an item is created. They did not.

What happend? Designer Workflows won't start if you're creating an item as a Farm Administrator or as a System Account in general. At least that's how it seems. Just use a second account and you are good to go.

Is this a normal behavior?
