The Dink Network

Although this might not be the problem, you could try to freeze dink and the well... (it will help to follow the dialogue better)
freeze(1); freeze(&current_sprite);
same for unfreeze @ the end of the script.
Your script should work since it is nothing wrong there. You could try setting &story to 0 before the actual dialogue (in the same script) to be sure that's not the problem.

void talk(void)
{
&story = 0;
... rest of script
}
