Hi Hippyjim Starbrook,

this is not the way you should do. It's better to use a wrapper to t
(he native function. First because you did not modify the standard
behaviour of prototype, and also because you still have the capability
to call the original function.
Have a look to the wrap() function at

In you case, you could do something like that:
      //do what you want here,
      //this refer to a Form.Element.Methods object.
      //call original method and return it's value if needed.
      return OriginalCall(this);

The OriginalCall is the original prototype function you overide. You
can (or of course not) call it.

hope that help.
