Pages are not automatically updating... why?

I'm using Promis*e V8i over AutoCAD2012 on a Windows 7 computer.  I'm having issues (seems to happen on copied projects), that pages are no longer updating.  For example, if I have a parent symbol placed on one page, child on another, and layout symbol placed, if I delete out one, the others are not updating when opening the other pages (like the parent page).  I have to manually update each page, then save, then navigate then update this page and so on.  Is there a fix to this?
