I think I found the bug, here's the change if anyone is familiar with the 
code perhaps they could double check my fix.

htmlimages.c
       int dice_x = 3 * s * ( BEAROFF_WIDTH +
                              3 * POINT_WIDTH +
                              ( 6 * POINT_WIDTH + BAR_WIDTH ) * i )
-        - 3 * ss * DIE_WIDTH / 2;
+        - DIE_WIDTH / 2 *  3 * ss;

-      int dice_y = ( BOARD_HEIGHT / 2 * s - DIE_HEIGHT / 2 * ss ) * nStride;
+      int dice_y = ( s * BOARD_HEIGHT / 2 - ss * DIE_HEIGHT / 2 ) * nStride;

        AlphaBlend( auchBoard +
                    dice_x - 3 * ss * DIE_WIDTH +
                    dice_y,
        ...

Looks like the / and * were a bit mixed up causing occasional int rounding 
errors - when the pointer is one out the reds change to greens etc.
