A simple workaround is to Return $GUI_RUNDEFMSG regardless, but it worked fine back in 3.2.11.5 and bugs in 3.2.11.9 (I don't have any versions in between for testing, sorry), I'm putting down the latest version simply because the bug is still present. This may be a duplicate of #222, but I'm not sure. {{{ #include #include Opt('GUIResizeMode', $GUI_DOCKBORDERS) $gui = GUICreate(@AutoItVersion, 200, 200, Default, Default, $WS_OVERLAPPEDWINDOW) GUICtrlCreateEdit('Control should size with window... but it does not.', 0, 0, 200, 200) GUISetState() GUIRegisterMsg($WM_SIZE, 'WM_SIZE') Do Until GUIGetMsg() = $GUI_EVENT_CLOSE Func WM_SIZE() Test() ;~ Return $GUI_RUNDEFMSG ; Should not be required, but if you uncomment everything works fine.
