Booklet prints pages in wrong order

I have Word 2007 running on Vista Ultimate. Since the upgrade to Vista, my
booklet prints pages in the wrong order. I have tried converting the
document to docx, and updated all the drivers to my HP Officejet L7880 and
they still print incorrectly. If I convert the document to a PDF and then
print the PDF from Acrobat reader in booklet form, no problem.

This one is making me nuts and I've been working on it for 4 months now.

Thanks,

Randy
