Answer 1

Here is something to consider: have you disabled selection somewhere in your code? If so, in some situations you may want to first enable selection, preferably in a mousedown event or before focusing on your element (NB!), before getting the range. Doing this has solved my version of the problem.

$('#MyEditableDiv').on('mousedown', function (e) {

    $(document).enableSelection();


});
