IE hangs while viewing BusinessObjects report in a new window

I get blank screen while viewing report with the option " In multiple full screen browser windows, one window for each document" under Set document viewing location

We have proxy setting with single sign on if I use proxy url. However it works fine if I access servername:8080 url.

Also it works fine if I set it to " In the BI launch pad portal as tabs " under Set document viewing location.

BO version: BO 4.2 SP3 .

Browsers: IE 11 , Firefox 55.0.3 and google chrome Version 60.0.3112.113 .

Please help.
