Sorry I hadn't posted back: I had a few problems with the PC.
Anyway, 'discard the new version and use the new version', lol
I meant 'discared the new version and use the old one', because people sent blank bodies as e-mails with the beta and so I wanted to stick with the reliable version. My e-mail is very important, see!
Anyway, I found just making Outlook 2007 'not available' did the trick. I love Office '07. It didn't hog any more ram than '03 when I checked. Live previews are cool, appearing instantly, and when I click away, the go away instantly! The GUI means my workflow is a lot quicker and my word processing is almost seamless! I love Office '07 and I want to buy it when the licence expires
