When you use 
    var ele = document.getElementById("theForm");
    ele.style.display = 'none';
    ele.style.display = 'block';
on a div (called 'theForm')
the values of any file upload controls are lost.
I will attach a testcase.

Cant tick the 
reassign bug to owner of selected component
(have changed component)
As when i submit bugzilla complains I am trying to change
status from unconfirmed to new even though I have not ticked
the confirm bug box!

This may be related to bug #179440 but I figure its a different bug as
this is hidding/showing a div with a form and 179440 is using innerHTML
to modify a form with a fileUpload.

WFM, build numbers and such indicate this is bug 152844, which was fixed a week
or so ago.
