Run the Windows troubleshooter

When an error occurs, such as “Does not respond because a script has been running for some time”, it can be easily fixed by running Windows Internet Troubleshooter to identify the genetic error. If the problem is already documented by Microsoft, this utility will automatically fix it if your version of Internet Explorer is having problems.

If you receive the “Not responding due to a long script” error message in Windows Internet Explorer, here are steps to follow:

  1. It is recommended that you download Windows Internet Troubleshooter.
  2. The Windows Internet Convenience Store will open after you click the .diagcab file you downloaded.
  3. Choose the Checkbox for Apply repair automatically on the first screen after clicking the Advanced button.
  4. The next menu can be accessed by clicking Next.
  5. Click Apply this fix to complete the scanning and repair process. Sometimes you might have to wait for it to complete.
  6. Test whether the problem has been resolved by restarting your computer.

The next step should be taken if this method does not resolve the problem.

Disable script debugging

It seems that the majority of concerned users who encountered the “No response due to long script” error message resolved the issue by making some changes to the Internet options.

Apparently, if the script debugging feature of Internet Explorer is disabled and no error notifications are displayed for each script, the problem can be completely avoided. In Windows 7, Windows 8.1, and Windows 10, this process has been confirmed to be successful.

Here’s how you can disable script debugging and prevent script errors from appearing in the browser’s Advanced Settings menu:

  1. On the top right corner of the screen, click the gear icon to open Internet Explorer 11.
  2. The Internet Options menu will appear after you click on the settings menu.
  3. On the top horizontal menu of Internet Options, select Advanced.
  4. You can disable script debugging (Internet Explorer) by going to Settings and scrolling down to Navigation. Then uncheck the Show script error notifications checkbox.
  5. Restart Internet Explorer 11 after saving your changes by clicking Apply.
  6. You can test if the problem has been fixed by repeating the action that caused it earlier.

You can proceed to the next possible solution below if the problem persists or you need another solution.

Removing a third-party security package

Internet Explorer 11 may have difficulties running certain scripts as a result of an overly protective anti-virus package, according to several affected users.

By disabling real-time protection or uninstalling the third-party security package, you can resolve the issue if you encounter the “No response due to long script” error.

You may be able to fix the problem by disabling real-time protection. Most antivirus suites have a menu in the system tray where you can disable real-time protection. With each program, however, the exact steps differ.

To make sure that the problem isn’t caused by a third-party package, remove the entire security package if this does not work.
