Hi Ken,

They are not part of the default install, I would guess that you must have installed the CustomUI plugin at some point?

Do you have any files inside your %AppData%\Moi\startup directory? By default that directory is empty, if it has the CustomUI files in there it would be because you installed it there and that is what makes those icons show up.
