This is indeed a difficult issue. When the selection is collapsed 
(nothing is higligthed, the cursor is just somewhere in content) and the 
RTE does not have focus, IE does not consider the selection object of 
this document to be valid (I think this is a bug in IE). This means that 
the RTE must have focus in order to update the toolbar. It is also 
needed when undo/redo snapshots are taken from time to time so that 
cursor position may be restored on undo/redo.

It seems however that it is not always the case that IE scrolls to the 
RTE that gets focus... I do not know when it does or does not.

When everything is complete, toolbar update is triggered. When toolbar 
completes is not known because every toolbar object is triggered to 
update its state.
