The web link is loaded in WebBrowser and throws Script error while the link is displayed in IE smoothly

I have a MFC application with CWebBrowser embedded.

Currently , I run into an issue :

my browser fails to load some web pages(lack of object , error about JS stuff) and always throws script error while the same web page cab be loaded in IE(10) successfully.

I also try to load it with Firefox and it's OK . So I suppose it is not caused by the page itself .....

As I know , WebBrowser has a parsing engine identical to IE . But why different behaviors ?

Please help me . Thanks in advance .

My OS : Win7 x64 + IE10 .

Solution

Thanks a lot.

Noseratio gives the correct answer. But his words is tagged as comments and unable to be rated .

Also , as the complement , For X64 version : the registry key is : HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION. I almost give it up because I am routed to : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION
