I'm on Windows 7 at home and XP at work. Last night, I emailed myself a document at home which I planned on going over at work this morning, figuring it would look exactly the same on both systems. My email attachment has opened with all the comments and changes my editor and I made still on display - which is how it was before I worked on it. My edits are still there alongside the comments so I haven't lost a night's work, but it still doesn't look as I expected.

Am I missing something or is this because of the two different systems?
