IE7 behavior when USB Token is removed

[ensoreus]

I'm developing a Java web application running on Internet Explorer 7 (client requirement). The application must all be SSL-enabled and the users must authenticate using an USB Token with their client certificate on it. If the USB Token is removed, the application must not be accessible anymore.

If I run the application on Mozilla Firefox 3, and I remove the USB Token (containing the client certificate), I get the following message:
Secure Connection Failed
PKCS#11 token was inserted or removed while operation was in progress.
(Error code: ssl_error_token_insertion_removal).

If I run the application on Internet Explorer 7 and I remove the token, the user can continue to navigate through the application like nothing happened (the same happens in Internet Explorer 8 for a specified amount of time; after that time clicking the application generates different JavaScript errors).

How can I get the same behavior in Internet Explorer 7 as in Mozilla Firefox 3 when the user removes the USB token?

Any help at all would be highly appreciated.

Thanks.
Andrei
