I am trying to open a web application but it returns with an error,
Unable to get property 'close' of undefined or null reference unified service desk
I am using IE process because my application runs in IE only. The application is called from a CRM page button click and is displayed in a pop up window.
Outside USD it works fine in IE 11. But inside USD it does not work and throws above error.
The web application calls ActiveX dlls so I am assuming inside usd it not allowing to call ActiveX. Is there any way this could be the reason? Or what could be the reason?
Also, if it is ActiveX issue then how can I fix it inside USD?
