I had a script program that used to do something extra whenever a function
was called in the page script. Did it this way.

          var oldRefreshTable = unsafeWindow.refreshTable;

          unsafeWindow.refreshTable = function(name)
          {
            oldRefreshTable.apply(name, arguments);

            newRefreshTable();
          };

So it called my function and I called the original and then my extra stuff.

Apparently this is not allowed.

How can I do this? I do not have access to the page script itself.
