It seems Chrome shows the cursor only on the padded area.
Try adding:
padding-left: 220px;
to the .drop_area_fileselect declaration in index.css, so that it looks like this:
.drop_area_fileselect {
	cursor: pointer;
	margin-left: -190px;
	opacity: 0.0001;
	position: absolute;
	width: 220px;
	padding-left: 220px;
}
