Without updating your system (of course it would be nice if possible to do so), a workround can bedoing this:
window.myCheckStatus="checked" or "unchecked".
You can change this value in any flavor no matter where you go and back as long as the window is not closed, this value remains. Then you can paste this value to a textbox or check if in JS. I am sure you can restore the check status when coming back. Try it.
Hope this helps. Thanks.
