This page contains following code (ubbc.js):
============================================================================
function AddText(text) {
        if (document.postmodify.message.createTextRange &&
document.postmodify.message.caretPos) {
                var caretPos = document.postmodify.message.caretPos;
                caretPos.text = caretPos.text.charAt(caretPos.text.length - 1)
== ' ' ?
                text + ' ' : text;
        }
        else document.postmodify.message.value += text;
        document.postmodify.message.focus(caretPos)
}
============================================================================
The value of expression (document.postmodify.message.createTextRange &&
document.postmodify.message.caretPos) is False on Mozilla. But value of same
expression is True on IE. Why this occurs?

Becase createTextRange is an IE-proprietary method -- see

Marking worksforme due to lack of a testcase (page is 404), but please reopen if
you have a testcase; if so, attach it to this bug.
