When using the trial version of Keynote2 that came with my iBook I occasionally get the following window popping up when I try to save:

"The following errors occurred while trying to
save this document:

type description

unable to save image pasted3.pdf


I think the problem is related to new master
slides created since the last modification; when
I get rid of the new master, there are no saving errors.

Strangely, though, if I keep the master and click OK on the error window and quit Keynote,
the changes are in fact saved the next time I open it. So this is probably not a big deal, just annoying because when I open the file it's looking for something called pasted3.pdf (or something like that), even though the new master was in fact saved. Anybody have a clue what's going on?
