It's hard to answer you without knowing more about your class/app.
I take it the code snippet is from KRImposerDocument? This is a
PDFView subclass?
What does skipToPage: do? Specifically, is it 1-based or zero based
(because PDFKit is zero-based).
I'm sure it's something I'm doing (possibly some autorelease
craziness?) since this snippet works fine when the document is
opened via the "Open" menu, and only happens when a new document has
been created programmatically from the originally opened one.
That bit puzzles me. How are you creating the document
programatically? There were small odd differences between Leopard and
Tiger here....
