Hello Simon,

thank you for the crystal clear answer and the nice improvement of my 
scenario. Yes, it was absolutely what I meant.

No, I just liked to know in advance how the rollback behaves. And it's 
perfect in my case that it does it the way you described.

Yes, that is what I meant. I am designing my app at the moment for 
single user, but keep a multi user setup in the back of my mind.
CDO makes this very easy, but it also has many advantages for single 
user applications.
I use the rollback for example to undo all changes of a bigger model 
that is modified by a large wizard dialog when the cancel button is pressed.

Best regards,
Kai
