Hi,
We are facing the same issue too and are still trying out different solutions.
In the below link, we have a helpful answer from Sriram
http://scn.sap.com/thread/3514304
however, it would only solve your problem temporarily.
The alternative solutions suggested in the thread are:
1. Application parameter to have value sap-ie=EmulateIE8
2. Maintaining this in webgui service
I am yet to try out the webgui service option, but the point 1 did not work. Further, please also cross check for browserdocument mode property and compatibilityview settings.
Please keep us posted once this resolves on your end, shall do the same if it works for me.
Regards,
Vinay
