test for presence of a callback? why would a callback "disappear"?

Hi.

I haven't quite been able to isolate a sequence of events that appears to
remove a callback, specifically a paste callback associated with a specific
document (that is, it's not a global paste callback).

I would like to be able to use ACL to test whether a callback is assigned.
It appears that I can ask by removing it and depending on the return code I
should be able to tell, but then I'd have to reassign the callback. Which I
guess isn't that big of a deal, but it seems messy.

Is there a simple, direct way to test for a callback?

Also ... has anyone run into disappearing callbacks before? What causes
them to disappear? The document is not closing/opening. It does lose
"focus" to another document that I create and delete, but it never goes
away.

Thanks!
