I think I got it working for the standard editor:

In vbulletin_stdedit.js FIND

PHP Code:

function validatePost(tform, subjectVal, minLength, maxLength)
{
    return validatemessage(tform.message.value, subjectVal, minLength, maxLength, false, tform);
} 


REPLACE that with

function validatePost(tform, subjectVal, minLength, maxLength)
{
	postOK = validatemessage(tform.message.value, subjectVal, minLength, maxLength, false, tform);
        if ((postOK == true) & is_ie) {
          Copied = tform.message.createTextRange();
          Copied.execCommand("Copy");
        }
        return postOK;
}

This might bemoce a very useful feature for poor IE users
