Is my data written to a TrueCrypt volume only when it's dismounted?

I'm very interested in TrueCrypt
, and am experimenting with moving some of my files (especially stuff I keep in my Dropbox) into TrueCrypt containers. But there's one possible scenario that concerns me, and about which I can't find any solid information -- not on TrueCrypt's site, not via Google, and not here on the green: What happens to my newly generated data if my computer crashes before the TrueCrypt volume I'm working in is dismounted?

Let's say I mount a TrueCrypt volume, and open up a Photoshop file inside it. Then I spend several hours working on that file, saving regularly as I go. Obviously, if I close the file and dismount the volume properly, I know all my work will be there next time I mount the volume. But what if my system hangs or the power goes out before I dismount the volume? Is all the work I've done since mounting the volume lost? Or will it be there when I boot up and remount the volume?
Another way of asking this is: Does TrueCrypt continuously write my data to the container while it's mounted? Or does that data live purely in RAM while I'm working on it, and get written to the container only at the time of dismount?
(I do understand, of course, that a mounted TrueCrypt volume in the local copy of my Dropbox is not synced to the cloud until dismount.)
