Yes, I know they *should* become normalized device coordinates, but they *don''t*. If the screen res is 640x480, my log file tells me that x=640, y=480, z=1 ... what the L? It makes no sense ... please help ...

Just a note: Never mind this issue. I''ve solved it by writing my own function ... the math actually isn''t very hard ...

Anyway, I''ve got it working perfectly. Thanks for all the help that was given!
