Hi All, I am trying to mark out the middle square of this Magnify Routine "window on right" (stolen from M23 - Thanks) - I assume the DllCall is overwriting the boxes. But wherever I try and redraw, they won't stay on the Magnify Window. Can anyone advise, bet way to keep boxes around the middle square. Please be kind with my code, it is ripped from a MUCH bigger exe. The "half" transparent window, is for dragging to where you want it, and the buttons are for more precise placement. #include <WindowsConstants.au3> #include <StaticConstants.au3> #include <GUIConstantsEx.au3> #include <WinAPI.au3> Global $hMag_GUI, $hMagDC, $hDeskDC, $hPen, $oObj, $aWinPos[2], $iLast_Mouse_X = 0, $iLast_Mouse_Y = 0 Global $pWindowCaptureX, $pWindowCaptureY Global $pWindowMagWinX, $pWindowMagWinY #Region - GUI3 ;
