cycles save render how to ?

how do you save render while cycles is rendering
F3 before was able to save render but now i get another menu !


I’m not sure if it’s the problem you’re having but image save during long Cycles render is apparently no longer unsupported in 2.64:

but you can stop it with Esc i guess then may be save wahtever has been renderer while doing F12 i hope!

that was usefull while doing long rendering in cycles !
