You want to note that as of the release of Vista, Windows no longer supports
these properties.
I meant 'FileProperties' here. What Excel is doing is populating
DocumentProperties using the FileProperties format. Somewhat confused?
The window that displays provides fields where you can enter these
values as 'DocumentProperties', thus the window's title. These will
appear on the 'Details' tab of the properties dialog. Note that the
'Keywords' field appears in the 'Tag' field in the properties list.
In Excel v11 and earlier, invoking the properties dialog displayed the
same as what you get when you right-click and select 'Properties' in
Windows Explorer. Not the case in later versions. Seems someone on the
Excel dev team got lazy when they configured this feature!
