No, you aren't the only one with problems. There's quite a bit of info on the topic if you Google it. One change I've identified is that options is now wordoptions in 2007. This affects several commands that set things such as background printing. Another big issue for me is that some templates don't work properly in 2007, even in compatibility mode. Things like margins are being ignored.

My client doesn't have Offrice 2007, I do--and I can't run their app! I'm hesitant to add lots of conditional code since it doesn't benefit them, it could slow the automation process even more, it will make the app harder to maintain, and the client won't want to pay for the work! I'm considering un-installing Word 2007.
