[TYPO3] error on mailformplus in ie

[Simon Browning]

One site I'm working with has two th_mailformplus forms.  One of them 
works fine, the other displays the below message at the top of the page, 
only in ie.

I could hack the class file, but is there a better way to handle this?

Thanks.

Simon
