MouseCoordMode "0" versus MouseCoordMode "1"

[mr-es335]

Hello,

May I ask why the following works with MouseCoordMode "1", but NOT with MouseCoordMode "0"

; -----------------------------------------------
#include <AutoItConstants.au3>
; -----------------------------------------------
Opt("MustDeclareVars", 1)
Opt("MouseCoordMode", 0)
; -----------------------------------------------
Global $iTimeOut = 100
; ---------------------
Global $hSAC_MAIN = "[CLASS:SAC_MAIN]"
Global $hSAC_FULLMIXER = "[CLASS:SAC_FULLMIXER]"
; -----------------------------------------------
RepositionSACTracks()
; -----------------------------------------------
Func RepositionSACTracks()
    ViewMenuSAC()
;~  RepositionO01SAC()
EndFunc   ;==>RepositionSACTracks
; -----------------------------------------------
Func ViewMenuSAC()
    WinActivate($hSAC_MAIN)
    ; -----------------------------------------------
    ; Select: Full Mixer View
    WinMenuSelectItem($hSAC_MAIN, "", "&View", "&Full Mixer")
    ; -----------------
    ; Resize: Full Mixer View
    ; Select: Right edge of F Mixer
    ; Move: Right edge of F Mixer
    ControlClick($hSAC_FULLMIXER, "", "", "left", 1)
;~  Opt("MouseCoordMode", 1)
    MouseClickDrag($MOUSE_CLICK_LEFT, 1907, 800, 368, 424, 0)
EndFunc   ;==>ViewMenuSAC
; -----------------------------------------------

Notes
1) Lines 1-28 work as expected with MouseCoordMode "0"
2) However, line 30 requires line 29 to "work"!
3) The SAC Full Mixer view requires a MouseClickDrag function and NOT a MouseMove function

Any assistance|advice would be greatly appreciated!
