Upload button not always working on Chrome

[bobinwood]

To fix it , I changed
ss.addStyles( this._input, {
'position' : 'absolute',
'right' : 0,
'margin' : 0,
'padding' : 0,
'fontSize' : '480px',
'fontFamily' : 'sans-serif',
'cursor' : 'pointer',
'height' : '100%',
'zIndex': 16777271, // instead of 16777270
});

var uploader = new ss.SimpleUpload({});
After initializing the simple upload add the following line end of the body.
uploader.updatePosition();
It's working fine for me.
