P3D v4....

[fsxwx]

I will definitely try to make it compatible.
However, FSXWX uses a FSUIPC Client DLL for .NET that probably do not work with FSUIPC5 (which will be released for P3Dv4). Furthermore, it is unclear if the offsets are still available in FSUIPC5 that I use for controlling the wind.

So, let's wait and see...
