Problem with office control UI element

Hi,

I have added office control UI element in my WD application. While executing it is pooping me a window with title as "SAP ACF TRACE". Also, in the browser it is displaying a window with the message "SAP IOS". Is there any setting from BASIS/PORTAL we need to make or any changes from ABAP/WD side we can do to fix it. Please advise.

Rgds
