It seems to be a problem with that web page when displayed in any app using an embedded IE instance on Win8. For instance, the MFCIE sample
http://www.kinook.com/Download/Temp/mfcie.zip (may also require
http://www.microsoft.com/en-us/downl...ils.aspx?id=29) has the same behavior. It displays the error message "Object doesn't support property or method 'attachEvent'", and UR does too if browser popups/dialogs blocking are disabled (Tools | Options | Browser). Not sure what that means.
