After I installed Excel 2003 on my machine, our IT guy also installed Excel
2007. Unfortunately 2007 now wants to be the 'default' version when I export
from other (non-Microsoft) applications and the files open automatically.

As I'm using Windows 7 and couldn't get Outlook 2003 to work, I have Outlook
2007 running, so don't want to remove Office 2007 from my machine.

I've run into problems before by removing single applications from Office,
so am wary of doing this.

Is there another solution?
