X/Y click on hidden window?

[Rux]

What I want to do is click a window relative X and Y coordinate in a hidden window. CONTROLCLICK() does not work, because you can only click visable buttons. How can I achieve this? Thanks.

(EX: I want to click coordinates 67,50 in the hidden window "Test.exe".)

You can try ControlClick but see Remarks:

Some controls will resist clicking unless they are the active window. Use the WinActivate() function to force the control's window to the top before using ControlClick().
