Maybe I needed a day before I could actually check if it works ?
Windows 10 Pro (10586.th2_release_sec.160223-1728)
WindowBlinds 10 (011 - Windows 10 Edition) - 64 bit OS
Wblind.dll 2016/03/24 15:11:37
Wblind64.dll 2016/03/24 15:11:18
Wbsrv.dll 2016/03/04 15:54:32
WB10Config.exe 2016/03/21 17:53:26
Wbload.dll 2016/03/24 15:11:18
Screen.exe 2015/12/02 15:52:27
Problem is still there, but my context menu problem is gone. 
Tried other skins, they have the same problem.
