    Check Everything is Clear

    Enabling Scripting in Internet Explorer 

    Before heading to the solutions, let’s see if JavaScript is allowed to run in Internet Explorer.

    Internet Explorer 6: go to Tools -> Internet Options, switch to the Security tab, and click the Internet symbol. Click Custom Level under “Security Level for this Zone." In the opened window, select Enable, which is under the “Active Scripting" option in the “Scripting" group. You will need to scroll to the bottom of the dialog to see the “Scripting" group. Make sure that Java is also enabled. Click OK to close the dialog and then click Yes when the security warning message appears. Click OK to close the Internet Options window.

    Internet Explorer 7: The steps are the same with Internet Explorer 6. Just make sure that the Enable option is selected under “Active Scripting" in the “Scripting" group. Also, enable the options that are related to Java.

    Unless you know what you are doing, do not check any other settings because this may have security consequences.

    Now we have enabled JavaScript to work in Internet Explorer. Close your browser and open it again to give it a restart.

    Seemingly Related Problems: Memory Leaks

    If you think that JavaScript in Internet Explorer doesn’t work correctly because it crashes, then the problem may be lying elsewhere. Internet Explorer 6 has memory leaks and crashes on normal events, which were solved with Internet Explorer 7. Upgrading your version of Internet Explorer should fix this issue.

    Seemingly Related Problems: Crashes on Sites with Flash Content

    This may be another issue which can misguide you to think that the Internet Explorer can not handle JavaScript. It may be due to the fact that the flash content present on the website may not be compatible with the Flash plug-in that you have installed on your system.

    Solutions to All

    To have a better Internet Explorer experience, make sure that you check the following items:

    1. Internet Explorer 7 is installed,

    2. Latest updates for Internet Explorer installed from Windows update,

    3. Plug-ins are the latest available ones (such as the latest Flash Player from Adobe),

    4. Shockwave Flash latest version is installed,

    5. Latest Java Runtime Environment from Sun is installed.

    If you go item by item and check everything works, then the problems you encounter will possibly be originating from the website’s coding or some other website compatibility issues.
