Hi. I'd like to use mouse in my program. I've compile GRX 2.4.6 with: USE_DIRECT_MOUSE_DRIVER=y USE_SVGALIB_DRIVER=y USE_FRAMEBUFFER_DRIVER=y Mouse in mousetest works fine. But when I compile my program: gcc -o chess chess.c -lgrx20 -ljpeg -lpng -lvga and run, it crash when I moved the mouse. Any idea what's wrong? Thanks in advance. Jacek
