Avoid reusing a window if it is the requesting window. This is useful for the "browse" button in the system browser or even for the "hierarchy" button in the hierarchy browser if the hierarchy is the same. A common yet simple way to duplicate a window without using a halo. Since this is an explicit user interaction, it is not expected to interfere with the "re-use windows" preference. I suppose. :-)
