No more memory and Framemaker stops

That is proabably not a great title...

Anyway,

Ever since I have gotten my 64 bit computer, FM has been awful. I have FM10, Windows 7, 16GB RAM.

When I make a pdf, it, of course as usual takes forever. But now it stops responding and never refreshes. I get an out of memory message sometimes, but I alwasy have to shut it down. Then to open my book, I have to reset every file in the book to use it and update...ect....

Is there something I can do?

It is only using 3.5 GB memory to make the file, so my computer isn't running out of memory.

Thanks,
