Hi Tamas,
Thanks for the response. I do not believe we have installed the latest "Cumulative Silverlight Client Patch" (Note# 2274219 dated 2-Feb-2016) mentioned in Master Note1964257 for Personas 2.0 SP3. I think we have installed only up thru Sep2015 (or Oct2015). I will ask our Basis team to install this latest one, then will re-test and report back (hopefully success :-). Thanks.
Jay.
