Hi, all I'm doing a new install of gpc with grx2.45 on a Win2000 machine. (1) The recent change in the compiler, from recognizing "integer(32)" to requiring "integer attribute (size=32)", means I needed to change line 59 of the grx.pas file accordingly. No biggie, just info. (2) My computer uses 1024 x 768 pixels in 16-bit color when running windoze programs, but the c-compiled modetest demo won't go higher than 1) 1024 x 768 x 1-bit, or 2) 640 x 400 x 8-bit. When I run the Pascal modetest.pas, it exits with error 1: GrSetMode: could not find suitable video driver. Am I missing some critical files? No windoze programs have complained about my video. thanks, Toby
