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.
