Redmine

Users can't add new attachment form due to Javascript error on IE 6 and 7.

It seems there's mis-use of the Prototype.js at redmine's application.js

On addFileField() method, "document.createElement()" method must be replaced with "new Element()".

function addFileField() {
  //...
  //var s = document.createElement("span"); // This should be changed as
  var s = new Element("span");
  //...
}
