Moving checkboxes through document

If you move a checkbox through the document by W3C DOM methods, the checkbox returns to its default state (checked or unchecked).

IE Windows uses the property 'defaultChecked' as its initial value.
So my guess is to have the 'onchange' event set this property equal to the 'checked' property, like this:

function checkIt(oInput) {
    if (typeof oInput.defaultChecked != 'undefined') {
        oInput.defaultChecked = oInput.checked;
    return true;

<input type="checkbox" onchange="checkIt(this);">

This bug seems to also apply when checkboxes are created dynamically.

This script, for example, creates checkboxes dynamically. If the initial state of these must be "checked", then Buberto's workaround must be used.

Radio buttons also seem to be affected by this bug.

This problem also occurs when cloning checkboxed.

I have just tryed the test page
that is supposed to show that
IE7 moves the check box but returns to default setting.

Well I guess that Microsoft has fixed the bug

Because i have
IE7 v 7.0.5730.11
