ElDiabloConCaca - thanks for that - I have a few of those messages which I will ignore.
And I think you have cracked my problem - I had my computer set to log out after 60 mins of inactivity - doh ! I don't remember setting this though - perhaps it is a default.
Many thanks.
Thanks Whitehill - I've had a look and found dozens of these in DATABAE SEARCHES - CONSOLE MESSAGES:

Hi, Macbook pro 2.4ghz, 4Gb ram, V10.6.4
I am experience repeated problems of apps closing in scenarios similar to this...
I leave 1 or more apps running, come back the next morning and wake the screen and find all apps closed.
Sometimes I can return and find all apps open as you might...
