Is anyone else having problems with IE11 and the Excel Web App? For example, opening a spreadsheet in SharePoint in IE11 and trying to select cells and move between cells takes a long time compared to IE10/Chrome/Firefox which are near enough instantaneous.
We've tried turning off GPU rendering, which made no difference. We've tried compatibility view, again, no difference.
We really need a fix to this as we're reliant on IE for other things and can't actually switch to another browser just as a workaround.
