Windows is stuck in an endless loop with an hourglass icon

[Dentist2026]

Hi everyone, 

I have a noob question: I have a fairly long piece of code, and I've simplified it to the bare essentials to illustrate the problem. When I click a button to trigger a function, I get a spinning hourglass icon in Windows.
Strangely enough, the AutoIT GUI works perfectly fine, but I'm sure there must be a small mistake somewhere in the code. Thanks.

Not so strange when you look at your code! 😉
You are overriding the standard cursor icon with the busy icon in the called func.

Try this version that will do that for 2 seconds and the return to normal:

    Sleep(5)
WEnd

Func F_LWR()
    ; Set hourglass icon
    GUISetCursor(15, 1)
    Sleep(2000)
    ; reset icon
    GUISetCursor(0, 0)
EndFunc   ;==>F_LWR
