One side: Office 2003 should run without issues on Vista. Even Office 2000 claims so. Maybe some of the issues were network issues?
The other side: You can save any Office 2007 document in Office 2003 format, and Office 2007 should be able to read 2003 documents.
So I'd start with Office 2003 on Vista until you get so many issues that it's unworkable. Then switch to Office 2007 and make the best of the compatibility.
The alternative: buy a laptop with XP and have your employer pay for a Vista upgrade once he upgrades his own machines. After all, it's in his interest if your private stuff is compatible with his.
Hope this helps.
I am purchasing a Dell desktop with Vista Home Premium.
I use excel ,power point, and word from Office 2003.
My employer also uses Office 2003 and said they had tried to use it in a computer with a Vista OS and ran into a ton of issues.
Until my employer upgrades from 2003, I must also use it. According to them Office 2003 programs won't work with Office 2007 programs.
Any information or direction will be appreciated.
