Why do some sites crash IE?

When I visit this site http://pmzilla.com/forums/pmp-exam-preparation/general-discussion-0 in IE9 on Vista, I get a popup that IE has stopped working.  It then refreshes the page.  Although sometimes it displays a page that it can't continue.  It happens about every other page click.

In Safari 6 on my Mac, it works fine (of course).  Any ideas what is wrong that IE crashes on the above site?  Is there a solution?

It's probably just IE9. Firefox probably works OK too. You might even "downgrade" to IE8 which is much more stable.

Happened to me as well. Got the same error message with IE9 & Windows7. Looks like the website is "not compatible" with IE9. Works well with Firefox & Chrome. I suggest Firefox or Chrome to view this website.

Not exactly a solution. Sorry.

Are there any reliable instructions for downgrading to IE8?

Try this


You can remove IE9 and install IE8 using the following steps.

1. Close all programs.

2. Click Start, and then click Control Panel.

3. Click Uninstall a Program under the Programs category

4. In the Tasks pane, click View installed updates.

5. In the list of installed updates, double-click Windows Internet Explorer 9.


Once Internet Explorer 9 has been uninstalled from your system, the computer will require a reboot. After rebooting, your computer should now revert back to Internet Explorer 8.

To disable IE8 or IE9 in Windows 7, go to Control Panel -> Programs. Click on the “Turn on Windows Features on or off” link. Uncheck Internet Explorer 9 (or Internet Explorer 8). The system will then act as if Internet Explorer is no longer installed. You can re-enable it via a simple checkbox.

brettr--I am getting this recently but infrequently.  It generally is a microsoft site.  I just click Cancel and everything continues normally.

Open Event Viewer and see if there is any info.  I keep forgetting to do that so cannot help right on that now.

Some sites crashes because of Active X incompatibilities try to click the comparability mode to right side of your IE navigation toolbar. Maybe try to either downgrade your IE or use other web browsers and make them as default browsers when asked.
