Many thanks
Ive hacked your code a bit ...
#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory.
LControl & WheelUp::
IfWinActive,ahk_class Progman
Return
IfWinActive,ahk_class Shell_TrayWnd
Return
WinGetPos,X,Y,Width,Height,A
WinGetTitle,Title,A
X := X-8
Y := Y
Width := Width+16
Height := Height+16
WinMove, %Title%,, X, Y,%Width%,%Height%
Return
LControl & WheelDown::
IfWinActive,ahk_class Progman
Return
IfWinActive,ahk_class Shell_TrayWnd
Return
WinGetPos,X,Y,Width,Height,A
WinGetTitle,Title,A
X := X+8
Y := Y
Width := Width-16
Height := Height-16
WinMove, %Title%,, X, Y,%Width%,%Height%
Return
this allows for the window to be positioned anywhere
also by not changing the Y the title bar stays still
