  1. This runs fine in 3.3.8.1 and did also as far as Beta 8 (and maybe later), but has not at least since beta 13 and through Beta 16. ;Global $hWnd = 0 Global $dpi = GetDPI_Ratio() MsgBox(0,"",$dpi) Func GetDPI_Ratio() Local $hWnd = 0 Local $hDC = DllCall("user32.dll", "long", "GetDC", "long", $hWnd) Local $aRet = DllCall("gdi32.dll", "long", "GetDeviceCaps", "long", $hDC[0], "long", 90) Local $hDC = DllCall("user32.dll", "long", "ReleaseDC", "long", $hWnd, "long", $hDC) If $aRet[0] = 0 Then $aRet[0] = 96 Return $aRet[0] / 96 EndFunc You can comment out the local declare of $hWnd and toggle in the Global, and still get the "Variable used without being declared" error on $hWnd. Did I overlook something in the release notes?
