Note; I tried with V2 (AutoHotkey_2.0-a098-59ec6aa.zip), and got the same symptoms, except the crash.

A strange bug if there is :-) System = Windows 10 64 bits - version 1803 AHK installation method = unzip in a directory Using = AutoHotKeyU64.exe Hotas Driver = Logitech 8.0.116.0 (latest), but not sure it really has any impact Specifics = remember that the X56 is a Hotas, so it has two USB devices ...

Excellent, thank you .. on to my post
