Hello everybody.

I have run into a problem when using an array of pointers
I declared it:

GameSprite *gsprite[SPRITES];

SPRITES is an const int. GameSprite is a class. (I think this makes an
array of pointers, i'm not positively sure about that.)

Anyway, i initialize them all:

  for(x=0; x<SPRITES; x++) {
    gsprite[x] = new GameSprite();
  }

Then they are used in a loop:

    for(x=0; x<SPRITES; x++) {
      if(gsprite[x] != NULL) {
        gsprite[x]->Plot();
      }
    }

The problem: The loop works once, the second time the last pointer in
the array just points to garbage. The problem doesn't seem to occur
when SPRITES is less than 255.

If anybody could help, i would be really greatful.
