Not all user preferences are saved? [OBD]

Hi,

I'm having a small issue with OpenBuildings Designer where some toolbars will always open on startup regardless of saved user preferences.

The toolbars in question are Family/Part Toolbar, Floor Selector, and Icon Locks. I've disabled them by using File > Settings > Tool Boxes and unticking the appropriate boxes as well as dragging them from the toolbar and closing them from the working area. Other user preferences are being saved (e.g. running other toolbars on startup and their positions, opening a second application window, etc). I've tried resetting the user preferences file by renaming it - this did reset the preferences, but didn't help with my issue.

Any help would be appreciated. I'm running OpenBuildings Designer CONNECT Edition Update 6 - Version 10.06.03.04.
