I have played around with this issue and found that the iframe (which holds the 
content that's editable) needs to be focused before the caret position can be 
properly read. This has changed in IE8 which is why you're seeing the behavior 
only in this browser.

Prepending the following to the ``IESelection`` function fixes the issue:

 function IESelection(document) {
    document.editable.focus();
    ...

However, it's not really a great fix because this seems to do a "hard focus" on 
the iframe which actually centers the browser on the iframe as a side-effect.
