This product is awesome when it come to the depth of simulation. But, God, i've never seen a product so buggy, at least in fsx::SE. Flickering, corruption on pause, corruption on welcome page in fsx, mouse out of focus all the time. I've this problem since the begonning. Support of PMDG of no help. Wow, at this price, unless you really need that level of simulation, this is a very bad purchase. If it was not a final sale, I'd ask for a refund right away!
