마우스를 다른데다 놓아도 변화가 없다면 만약 메뉴1에 마우스를 올렸다가 메뉴2에 마우스를 올렸는데 1번의 서브와 2번의 서브가 다 나와 있겠죠.
흐음.. 혹시 말씀하시는게 각각의 페이지에 들어갔을때 서브가 보이게 하는것 아닌가요?
그런 경우라면 각 페이지마다 레이어 메뉴의 설정중 기본으로 서브를 보이도록 하는 방법은 있습니다만.. 질문이 난해해서 낭패.

레이어를 만들어서 서브1를 만들어넣고 메뉴1 위에 마우스를 올리면 그 메뉴가 뜰
위치에 올려놓으신 후 hidden을 넣어주세요. 그다음 메뉴1 이미지에 onmouseover을
넣어주셔서 서브1 이 뜨도록 하면 됩니다.;
