I translated two functions from the WinAPI to AutoIt, so we can create transparent windows without any images. Therefore, we call _WinAPI_SetLayeredWindowAttributes with $i_transparentcolor set to the bg-color of the GUI and ... the background is gone CODE#include <GUIConstants.au3> #include <Constants.au3> #include <WindowsConstants.au3> #include <WINAPI.au3> ;############# Constants ########## Global Const $LWA_ALPHA = 0x2 Global Const $LWA_COLORKEY = 0x1
