I have a 175kb 2 page PDF file that I am updating a field in. On save, memory usage soars from about 300MB to well over 2GB causing massive memory swapping on my laptop which is configured with only 1GB of memory. I have trimmed down all necessary processes and this still happens and only when I try saving under Acrobet 9 Pro so I am pointing my finger at it. I am using a trial version of it which I am very happy about since I would not want to purchase this product if I can not save files. I have a Dell Latitude D520 with Intel Core Duo 1.66GHz CPU, 1GB memory running Windows XP Pro.

I turned off "optimize for fast web view" with the same results. I may see if I can find Acrobat 8 and see if I have the same issue.

Ok, it is indeed Acrobat. It seems to do this sort of thing sometimes,
but you might find that turning off "optimize for fast web view"
helps.
