If that was the case, wouldn't the pre-app callback be made at least once?
It isn't called at all.
I forgot to mention that this is a cliptexture application.

Do you share the APP callback between channels (pfChannel::setShare) ?
pf2.2 contains a bug: When you share the APP callback between channels, all
the sharing channels call it.
The correct behavior (in the man page): When you share the APP callback
between channels, only the master channel calls it.
This bug was fixed somewhere between 2.2 and 3.0 (I think it was 2.4.x).
Can this be the problem ?
