I wanted to try out this new Internet Explorer 9 since I was very sick and tired of IE6,7,8 being slow. I use Windows 7 Professional (EN) but mainly I go to Korean websites. After I installed IE9, it was okay if I access yahoo.com or mlb.com but it stops working (msg : "Internet Explorer has stopped working") whenever I go into daum.net, naver.com (which are all Korean websites) I wanted to report this to IE9 beta testing center (or whatever the name is..) but it's always to find something really REALLY darn hard in microsoft.com (it's not user-friendly at all!!) Does anybody know what is the problem with this? I'm sure there's nothing wrong with my laptop. It works fine with IE8 or Chrome. On the background, I use V3Lite which is a Korean anti-virus, instead of MSE. (much lighter software) Thanks

Hi, May I know if the issue occurs on certain non-English sites? If so, please also let us know the URLs. Due to Internet Explorer 9 is a BETA version now, it may be an incompatible issue. I would like to suggest you try the following method to troubleshoot this issue: 1. Reset Internet Explorer 9to default settings. 2. Remove temporary Internet files, browsing history data, and Web form data. 3. Opens Internet Explorer 9 in No add-ons mode to test the result: Click Start àAll Programs à Accessories à System Tools à Internet Explorer (No add-ons). If IE9 work normally in this mode, then we can identify which add-on lead to the crash: 1) Click Tools on the Internet Explorer toolbar, and then click Manage Add-ons. 2) Click the name of the add-on at the top of the Toolbars and Extensions list, and then click Disable. 3) Click Close, and then test Internet Explorer. 4) If the problem still occurs, open Manage Add-ons, enable the add-on that you disabled in step 2, and then repeat steps 1 through 3 for the next add-on in the Toolbars and Extensions list. 5) Repeat steps 1 through 3 until the problem is resolved or until all the add-ons have been tested. 4. Perform a Clean Boot. Hope it helps. Thanks.

I figured the problem. It wasn't about the add-ons. The particular sites were like http://daum.net, http://naver.com These sites contain Flashes. (Since it's a Flash, it could be a add-on) But, when I went to Internet Option and turned on "Software Acceleration instead of GPU", no crashes occured to my new IE9. Probably, this new option does not cope with Flash on the web.
