I had reported two issues in v4. My Polar USB 2 IRDA adapter stopped working (it was OK in v3). DirectDraw was broken on my v2 Macbook Air, so with DirectX turned on then WMVs and HavaPC gave sound without video. I updated to 4.0.3810 today and it fixes both these issues, so it is a Happy New Year from the Parallels team to me Thanks guys (well and gals)!
