Hi again,

You are absolutely correct: it's only a problem when using Adobe Reader. If I use Foxit Reader, everything seems to work. It's sort of a strange problem to encounter; I would've expected Acrobat to be the one that does work, since MS would likely have tested the heck out of that viewer because it's the most commonly-used one. Oh well, I'm happy to use Foxit rather than Adobe anyway!

Thanks a lot for your help, although this appears to be a bug... and bugs are notoriously impossible to report to MS. I'll still mark this as "resolved" since there is a freeware solution to the problem that others may appreciate finding.
