Mouse position in OpenGL ( again )

Hi,

Like some others, I am currently developping an OpenGL game.

If you want to see a early release:
http://www.multimania.com/nitrocodecorps/facehimteam/2002_01_13_ShakyIdiot_Release_0.0114.zip

And of course, I have some problems with the latest version of the library to know about the mouse screen position while running in fullscreen.
So please, can somebody could solve the problem ??
[ With the version 1.2, I had problems initialising joysticks, it’s why I would prefer using the 1.2.3 ].

Thx,
Bernard LERAT.
