Hello Community,

I have following small C code, compilable with gcc 4.7
and the new version of the GRX 280 libarie

#include <stdio.h>
#include <grx20.h>

static GrContext *grctx_global = NULL;
static GrContext *grctx_win = NULL;

int main(int argc, char **argv)
{
  char text[256];

  GrSetMode(GR_width_height_color_graphics, 800, 600,24);
  GrClearScreen(GrAllocColor(0,64,200));

  grctx_global = GrCreateSubContext(100,100,400,400,NULL,NULL);
  grctx_win   = GrCreateSubContext(10,10,150,150,grctx_global, NULL);

  GrSetContext(grctx_global);
  GrClearContext(GrAllocColor(0,200,164));

  GrSetContext(grctx_win);
  GrClearContext(GrAllocColor(0,255,0));

  while (getc(stdin) != 'b');
  GrCircle(100,100,20,GrAllocColor(255,255,255));

  GrResizeSubContext(grctx_win,100,100,150,150);

  while (getc(stdin) != 'q');

  GrSetMode(0);
}

The Problem is, that i can't realize that the win context is
not moved or resized.
What make i false - any tips are welcome.

Thank's
Jens
