1. (Posted Oct 24) Remove the vertices field from the AnimObject struct in objects.h
2. (Posted Oct 24) Change the following in animgui.cpp.

              from:
                 glOrtho(0, WINDOW_WIDTH, -WINDOW_HEIGHT, 0, -1, 1);
              to:
                 glOrtho(0, WINDOW_WIDTH-1, 1-WINDOW_HEIGHT, 0, -1, 1);
            

3. (Posted Oct 25) Retraction of #2. If you never made the change in the first place, then just leave it alone; the original was correct. If you did change it, then change it back, as follows.

              from:
                 glOrtho(0, WINDOW_WIDTH-1, 1-WINDOW_HEIGHT, 0, -1, 1); 
              to:
                 glOrtho(0, WINDOW_WIDTH, -WINDOW_HEIGHT, 0, -1, 1);
           

4. (Posted Oct 26) In animgui.cpp change the following for the second loop in the LoadObjects function.

              from:
                 for (j=0; j<objects[i]->numVertices; j++)
              to:
                 for (j=0; j<objects[i]->numKeyframes; j++)
