new IE instance opening periodically when SSRS report open

Hi All.
Few people is receiving this strange issue and I cannot find any
resolution for this.
Issue is exactly with subject. It's happening only when SSRS report is
opened.
So it's opening a new window with this url:
https://website/ReportServer/Reserved.ReportViewerWebControl.axd?ExecutionID=ui2iiomxhroymbrzv5p5aymx&ControlID=5b14ab22-5967-43af-a9bf-ab75feea60ba&Culture=1033&UICulture=9&ReportStack=1&OpType=SessionKeepAlive&Interval=1139000
Any idea what setting may be causing this strang behaviour'
Thanks,
