Now (2014/13/18) Microsoft does not more support Win XP

What date notation is this? Is it the 13th or the 18th month of the year? 😉
Anyway, the magic date is the 8th of April this year, so still three weeks to go.
But Win XP is still widely spread and used and this will not change all in a sudden. And there will still be support for a while.
But of course I agree fully - we need urgently full Win 8.1 support in the next maintenance release of Mathcad 15. As Prime isn't ready work work, MC15 must be ready for current OSs.
