Hi Patrice,

Got two ideas :
1. addEntryToObjectCache(filename, new MyDummyEmptyObject());

2. addEntryToObjectCache(...., 0.0001); removeExpiredObjectsInCache();    (if 
and only if this does not interract negatively with the rest of your app).

I personnally prefer the first one.

If it still doesn't work, try using a debugger and trace when the image gets 
referenced.
Cheers,
