[jQuery] [validate] opera shows no errormessage

Hi Jörn,
I´m a jquery-beginner and try to build my first form with your
validation-plugin.
I appreciate your great work!
Everything works fine, only opera in version 9.51 shows a strange
behaviour:
I validate the fields onblur and show a ok-image onsuccess.
When i leave a invalid email-inputfield, opera don´t show the
errormessage.
The inputfield itself has the errorclass - i can see this because there
´s a red border from my css.
But the errormessage don´t appear.
When I click submit, or I leave any other inputfield with a valid
value, the errormessage for the emailfield appears.
Here is my code:
$(document).ready( function()    {
    /* check the formfields */
    $.validator.setDefaults({
        success: function(label) {
// set as text for IE
label.html(" ").addClass("valid");
}
    });
    $('#regForm').validate({
        rules: {
            vorname: {
                required: true,
                maxlength: 100
            },
            name: {
                required: true,
                maxlength: 150
            },
         email: {
            required: true,
                maxlength: 150,
            email: true
        },
            emailcopy: {
            required: true,
                equalTo: "#email"
        },
            username: {
            required: true,
                maxlength: 30
        },
            password: {
            required: true,
                maxlength: 40
        },
            passwordcopy: {
            required: true,
                maxlength: 40,
                equalTo: "#password"
        }
        },
        messages: {
            vorname: {
                required: "Bitte geben Sie Ihren Vornamen ein.",
                maxlength: "Der Vorname darf höchstens 100 Zeichen lang sein."
                },
            name: {
                required: "Bitte geben Sie Ihren Namen ein.",
                maxlength: "Der Name darf höchstens 150 Zeichen lang sein."
                },
             email: {
                 required: "Bitte geben Sie Ihre E-Mailadresse ein.",
                maxlength: "Die E-Mailadresse darf höchstens 150 Zeichen lang
sein.",
                 email: "Bitte geben Sie Ihre E-Mailadresse im Format
name@domain.de ein."
             },
            emailcopy: {
                 required: "Bitte wiederholen Sie die Eingabe Ihrer E-
Mailadresse.",
                equalTo: "Die beiden E-Mailadressen stimmen nicht überein."
             },
            username: {
                required: "Bitte geben Sie Ihren Benutzernamen ein.",
                maxlength: "Der Benutzername darf höchstens 30 Zeichen lang sein."
                },
            password: {
                required: "Bitte geben Sie ein Passwort ein.",
                maxlength: "Das Passwort darf höchstens 40 Zeichen lang sein."
                },
            passwordcopy: {
                required: "Bitte wiederholen Sie das Passwort.",
                maxlength: "Das Passwort darf höchstens 40 Zeichen lang sein.",
                equalTo: "Die beiden Passwörter stimmen nicht überein."
                }
        }
    });
});
Is this a bug, or my mistake?
There is a second question I have:
When there is the attribute 'maxlength' in the html of the inputfield
I want to validate,
the rule 'maxlength' seems no longer be working.
(I tried this with a maxlength of 10 in the rule and maxlength of 20
in the html attribute.)
Is this a bug or is the rule overriden by the html attribute?
Can you help me?
