> The html version of the CAS Viewer (as used by the Document Analyzer, if you select html
as the format) uses Javascript to display annotations in the right-side pane on mouse-over,
and resets this when the mouse moves out of the item on the main pane.
> The reset is done using the frame's document, via doc.close() and doc.open().   This
clears the annotation pane OK, but the open() causes a History record to be created.   
> This is compounded by the fact that a word may be covered by many annotations, and there's
one of these clear actions for each covered annotation.  So if you have 6, moving out causes
6 resets, and 6 additions to the History.  This rapidly make it appear that the "back" button
is broken...
> Use a different reset method to avoid overloading the history list.
