Hi,
That is very puzzling - I agree.
Can you find out at what point it stops working properly?
That is, you've tried it with 3 and it works, but with 30 it doesn't.
Can you narrow it down to "it works with N but not with N+1"?
It could be a problem with image N+1 in that case.
To check this try excluding that image and see if it works for
all the remaining ones (i.e. 59 of them).
If it isn't that it may be a Mac idiosyncrasy in which case the number will
help. I'm sure there will be a way to fix it in either case, but we'd
need to know which it is.
All the best,
Mark
