Microsoft's usability dementia started with them removing the 3D relief from toolbar buttons in Windows 98 to look like plain icons and making menubar labels indistinguishable from toolbar buttons (except text instead of icons) just for the sake of looks, despite all these having different user interactions. Then again they were never completely consistent. For example in Win3.x design 3D elements were supposed to be for those that cause some command to be performed, yet the scrollbar visual design was the same as that of buttons.
