The fix for this requires some special handling of the case where the offset is 
beyond the end of the child nodes within the container.  My company (Pearl 
Crescent) has applied several fixes to convertFromDOMRange, including one for 
this issue.  I will attach the code we are using.

We had a contenteditable field with some <em>'s inside.

This fix
line 82
-  cursor.compareEndPoints(bStart ? 'StartToStart' : 'StartToEnd',
textRange) > 0

+  cursor.compareEndPoints(bStart ? 'StartToStart' : 'StartToEnd',
textRange) >= 0

and that
line 85
-  if (cursor.compareEndPoints(bStart ? 'StartToStart' : 'StartToEnd', 
textRange) == -1 && cursorNode.nextSibling) {

+  if (cursor.compareEndPoints(bStart ? 'StartToStart' : 'StartToEnd', 
textRange) <= 0 && cursorNode.nextSibling) {

helped us much.

Win 7, IE 9.
