You could also use the session checking logic NativeBoost uses. Take a look at NativeBoost>>sessionChanged et al.

Sorry, my last email is UNREADABLE!

Here is the spellchecked version:

Hi,

I want to persist some value (in a singleton), but when a user creates a copy of the image, I want to regenerate that data, so there will be no two images with the same persisted data. Is there some way to act on an image launch? Or maybe you have better suggestions���
