蛋糕目录中是正常的，在关于我们里就弹一下就没了显示
你这些在哪。。
我这ie8和火狐都没什么反应
我的资源里有纯css+div的弹出菜单，可供你参考。
会不会跟事件冒泡有关？你去网上查查怎么JS阻止事件冒泡，应该在弹出框显示的代码后面加上阻止事件冒泡，就会好了。
事件冒泡与浏览器有关，具体写法，网上也都找得到的，我从前在工作中也遇到过类似的情况。。希望可以帮助到你。
我佩服你的勇气啊，看到你写的html，好像是直接在dreamweaver里操作的弹出隐藏，太复杂了，且不易维护更新，去学下div+css+jquery，图片的切换现在很多都是用css sprite（把一些琐碎图片放到整张大图片），做成背景的切换，导航弹出同隐藏也比较流行的是jquery实现效果
