Internet Explorer IE 10 Form Fields Dissapear

[Anonymous]

Has one anyone else seen a bug on Marketo forms when using IE - where if you hit the "Submit" button without filling out any fields some form fields will dissapear?  Or when you hit the "backspace" button the form fields will dissapear?

You might want to check the source code and Css (use FireBug). Most likely they do exist, but there is an css error.
