when I'm located in OLAP Design mode and trying to click the design button in the header again or the Admin button nothing happens. In IE I activated debug mode, followed the steps above and got following error message: "Invalid Argument in Popup.js"
The following section of the code was marked as the cause: this.div.style.top=(d.y+h)+"px"
Is it possible that the cause of this problem is some browser setting in IE11? In Firefox 39.0 I am perfectly able to click on Design or Admin without a problem, when I'm already in Design mode.
