Web-to-Lead form problem: using the space bar jumps to next web page

Web-to-Lead form problem: using the space bar jumps to next web page

I have made web-to-lead forms in the past that all work perfectly in the websites they are on.

But it has been awhile and now seems the new code generated is causing the use of the space bar, while filling in the form on the website, causes the page to suddenly change, rather than just giving the user a space while typing.

I checked my old forms on my sites and they still work fine.

Can anyone suggest anything, or is there a bug in the current form code being generated when creating the form?

Thanks,
Paul
