[ Outline ] · Standard · Linear+ Memory for appz

ok, even as i type this, my processes menu is telling me:

im right in the middle of working on a 345 Mb Photoshop file, and i havent saved for about 2 hours. as you can imagine, i dont want to loose any of my work. but, upon editing a large amount of type, PS freaked out and started to freeze, and is giving me the dreaded [Not Responding] next to the app name.

Now, the Mem and CPU usage for PS is still going up and down as if it is processing, and i got an error before saying my comp had to increase the size of its Virtual Memory for the Page File Usage History.

What i want to know is, is there anyway i can hold onto my work and not force quit Photoshop? If i leave it for long enough, will it sort itself out? Can i increase the memory available to PS and the Page File History, so it will finish its process? Is there anything i can do?
