Thank you, mouser and Target. :) The DllCall relied on having a valid hWnd for the script's window, but it was written based on the script running in the AutoHotkey interpreter, not compiled independently.  The class was still the same, but the window title wouldn't match anymore because the title of a compiled Autohotkey script's window becomes the path to the executable (unless otherwise set).

Finally figured it out.  The FindWindowEx call in LockDetect.ahk wasn't finding a valid hWnd for the script after compilation.  Changing the values in that call fixed it.

@jpprater
What was the change you applied? Can you please post new code? Thanks

jpprater:
This code right here in LockDetect.ahk:

--- Code: Autohotkey ---hw_ahk := FindWindowEx( 0, 0, "AutoHotkey", a_ScriptFullPath " - AutoHotkey v" a_AhkVersion )This had to be changed to accurately reflect the title of the compiled script's window.
I don't have the code available to me just now, but I'll post it tomorrow.  If you compile the script yourself and try to run it, and then open the script's window, you'll see what the proper title to match is.

This is the updated LockDetect.ahk.  Changes between this version and the original are on line 46 and the additional constants on lines 29-39.

That was exactly what I was looking for, big thank you!
