I have not seen this happen, but something is changed since last patch day.

I fill huge amounts of cells with the array operation. Since last week this is considerable slow. Transfers that has run within minutes now need one and a half hour. Customer came up with this, so it's not only with me ...

I run Win 8.1 / Office 2013
