Analysis Application TAB's not working

Hi folks,

I have created a design studio dashboard(DS version 1.5) which contains multiple TAB's and saved it in the BI platform.

I am open to view the Analysis Application from BI platform, and click on all the TAB's thru IE.

But my client is unable to click on the TAB's when she tries to open it from IE (version 11)

When she clicks on the TAB's no action happens.

She tried it using mozilla firefox but still the issue persists

Any idea on what could be issue here?

Regds,

Samson
