validate problem with IE11 Enterprise Mode

validate problem with IE11 Enterprise Mode

i develop a corporate intranet site and i make good use of jQuery, jQuery.ui, and jQuery.validator.
our standard browser is IE8... but we've been asked to do compatibility testing with IE11 (with Enterprise Mode, which emulates IE8) and Chrome.

the result:
- Chrome: FUNCIONA
- IE8:  FUNCIONA
- IE11 without Enterprise Mode:  FUNCIONA
- IE11 with Enterprise Mode: jQuery Validation *NO* funciona

yes, the only problem occurred in IE11 *with Enterprise Mode*.
when i click on Submit, IE11 (Enterprise Mode) ignores the validation rules and submits the form with invalid data.
at no time do i see any error messages.

has anyone else seen this problem?
would appreciate any guidance or ideas. :)
btw i know that jQuery.validator HAS loaded:
typeof(jQuery.validator) != 'undefined'

below are the headers that i'm using.

thanks! robert
