It seems FSX add-ons are hit by this bug. FSX and all original menus/windows works fine, not tested all though. But when I click on one FMC to open it as a separate window, I get the error that a child window cant be created and FSX slowly crashes and drags Active Sky 2016 with in the fall. The same happens when i try to start FS2 Crew menu or GSX Ground services.
I have both QOTSII and 737NGX.
EDIT: This bug appeared today after Fall creators update. Clean install earlier this week, worked perfectly until Windows 10 update.
I run FSX:SE by the way.
