When I use publisher it almost always says not responding when I open it or when working on a file with several pages, when I change from one page to another. There are times when it will finally open after a minute, other times it locks up. It is also extremely slow. This is the same on another computer I use it on. I have Windows 7 with an AMD FX 8120 eight core processor 3.10 GHz with 16 GB of RAM on a 64 bit operating system. I don't understand why this program is so slow and locks up.
