Page with two+ forms - submit on enter not working?

Oke, have strange problem :-)

When you have more then 1 form on the page (using CI form helper) browser will only submit last form on enter key (on keyboard).

So, if users is on the i.e. first form on the page, he fills the data in and hits enter - nothing happens :S

Workaround is to place a form_submit(); button (emtpy works as well) in a hidden <tr> inside that form. But, that's not quite what I like, to make messy code

Is there a 'legitim' work around this problem?

Cheers,
