I Steps: Go to https://www.ebanking.hsbc.com.ar/default.asp II Issue: typing the user id a pop up error appears for every key pressed. III Conclusion: When a key is pressed, IE doesn't execute the "window.onkeypress" handler, FF considers the "window.event.keyCode" as error and thus ignores the alert, Chrome/Safari can execute the handler successfully. IV Other Browsers: IE7: ok FF3: ok V Nightly tested: 37604

I think behavior has been changed across all other browsers and now they match with Safari 15.6 on macOS 12.5 in this test case and show "pop-up" / dialog box on each key press. Since all browsers are behaving same, I think this can be consider as "RESOLVED WONTFIX". Thanks!
