Steps to reproduce

I embed .Net WebBrowser control into my Win32 application. If I load HTML file with JavaScript code that executes endless loop, whole my GUI freezes. You can reproduce this issue using attached Demo application. Run the application, specify path to the TempLoopLaunch.html file, click the Go button, click the Delayed Alert button. You will notice that whole app freezes. If you do same actions in MS Internet Explorer, you will notice that MS IE doesn’t freeze in this case.

Could you please let me know if it’s a bug in .NET WebBrowser control, or maybe I need to implement something special to get same behavior as in MS IE?

  • Hello,

    Thank you for providing your feedback on IE11.

    We are not accepting feedback on Internet Explorer through this portal any longer (unless security related). We welcome any feedback you have on Microsoft Edge using this website. This item will be closed as not repro since I was not able to get the same crash / error reproted.

    Also, if it helps the repro provided did not freeze my computer - at least not permanently. I eventually received an alert with a large number in it.

    All the best,
    The MS Edge Team
