在一个职责中要想同时打开多个窗口，我们一般都是把工具－－下面的的“关闭其他表单”的选项去掉就可以了，可是有个时候，这个选项是灰色的，不能修改。那么我们可以在职责定义过程中，在菜单排除项中将“浏览器：禁用多表单（ Navigator: Disable Multiform ）”这个功能排除掉就可以了。
The values are stored in FND_USER_PREFERENCES table by user. To see whether the checkbox is checked or not:
select * from fnd_preferences
where preference_name = ‘NEW_WINDOW_FLAG’
‘N’ means defaults to checked, ‘R’ means defaults to not-checked. We have had some inconsistencies with this checkbox. You would un-check it and exit the applications, and the next time when you log in, it’s checked again.
