        Hi,
thanks for looking on this. I've been wondering why it is so, but I've
never got to the point of checking where the actual problem is. I
thought the problem is that some object is overwritten, which shouldn't
be (I thought about the Info), but I won't expect it being the XRef
table, because that one is supposed to be updated, due to added
objects.

Two questions: a) did you do it manually, or you've some sort of a
"shareable" code, please? b) Does it apply only to this sort of the
document, with an XRefStream, the other documents will still misbehave?

        Thanks and bye,
