Vista Small business (up to date)
Excel 2007

Windows Speech Recognition is excellent!! That said, I can not get it to work with Excel 2007 when
in Vista . In contrast, I have Excel 2007 on an XP machine and the Dragon Naturally Speaking works
as expected.

When in Excel, in a cell, if I say i.e. 1000 I get the question "What did you say?"
If I say "Account number" it asks "What did you say?"

If I use Notepad, Word, what ever; Windows Speech Recognition gets it correct!!

What am I obviously missing when using Excel?

I realize that answer is probably stupidly easy.

Any help appreciated!!

BTW, I have rebooted etc.
