The compact maintained is the culprit, there is a file in there that shouldn't have been there. One of the things left to fix for me tonight. It will work for the release, don't worry.
The window you want removed is the player window. If you remove the file the player window from the DefaultUI pops up. However, I can add an option (another .zip, hehe) that permanently removes it (remind me again should I forget to put that into the release, you never know

).
