The IE Compatibility view is not supported

Hi Guys

We are using Lean Orders in CRM UI and when we click the Invoice document hyperlink in Transaction History of Credit Memo  and give ECC credentials we get the below error :

"The IE Compatibility view is not supported ( Note 1970689)"

We checked the Note 1970689 but it did not fix the issue .

Can any one guide us if you guys have come across the same issue ?

We are using Internet Explorer 9 and CRM 7.0 EhP3.

Any inputs are highly appreciated.

Regards

Vinayak
