I've grepped the web folder and couldn't find any reference to the style tag in the Dimension column. Those inline css statements are overriding the ColumnHdg class, but I can't seem to find where that is defined. It doesn't appear that any of the files have changed in the msgdb or res folders (timestamp is that of the install date).
