		Hello everybody,

	I have got some (strange) problems with  the grn-drivers and the 
	grx-library.
	
	Everything works fine as long as I am using the et4000k.grd
	(for the graphic card I have got in my PC), 640x480,
	800x600,1024x768 no problems at all, 
	but when I try to use the vesa.grn, vga16.grd or stdvga.grn
	the 640x480 (16col)mode simply does not work.
	I tried GrSetmode() with
		GR_width_height_graphics,	
		GR_width_height_colors_graphics,
		GR_default_graphics,
		Gr_biggest_noninterlaced_graphics,
	the screen always shows 320x200 graphics ( at least it looks
	like this) and the whole graphics output get screwed up.

	I am using Cplusplus; could this be the problem ?
        

		Thanks for any help,


			Eric
