krisddd, Welcome to the Autoit forum. From what I can see from the thread, GhostIt does not pass clicks. So drawing a GDI grid might be a better bet as this does allow clicks to pass. Perhaps something like this: #include <GuiConstantsEx.au3> #include <WindowsConstants.au3> #include <WinAPI.au3> HotKeySet("{ESC}", "On_Exit") Global $hGUI, $aRadio[5], $hButton, $iStep $hGUI = GUICreate("Grid", 150, 190) GUICtrlCreateLabel("Choose a grid step value", 10, 10, 150,
