Hi, element has found a error in the code for making the dialog box. The code is fixed. The error was in the line : if (!CreateGLWindow(Titre,Resolution_X,Resolution_Y,16,fullscreen)) ==> You can only choose a 16 bits The line fixed : if (!CreateGLWindow(Titre,Resolution_X,Resolution_Y,Bits,fullscreen)) Thanks element. ======================== Leyder Dylan http://ibelgique.ifrance.com/Slug-Production/
