Strange problem here. On a brand new windows 8.1 computer excel opens incorrectly at times. The user has an open excel-workbook along with his outlook open. When trying to open another excel document attached to an email in outlook, about 50% of the time, the new excel-documents open as an empty excel-window. When I say empty I really mean empty, there not even the workbook-area showing, just the borders of the excel software, all other fields are blanc and see-through. Any ideas of what this could be?
So far we have tried uninstalling Office 2013 with microsofts own fixit, Also tried "Launch folder windows in a separate process" from within Windows Explorer, and also changed the DWORD-value FOREGROUNDLOCKTIMEOUT to zero according to google.
